Harrington ricks  Account Info

I would like someone to make a math program for numerical analysis for advanced math classes. I do know this would be an easy program to make, although, I need to know how to start it and if someone could show me how to start it, I could make one and then put it on the site. I have a TI-83 or TI-92 Plus. So if you have any ideas, contact me asap.

Hey. So what kind of Advanced Math Classes are we talking here? I could help but I would need equations on what you are talking about then, I could send you the information you want and need to get started then you could do the rest.

If You are looking for distance formula, and have a ti-89 then you could download mathwiz.
It has a program in it which figures out the distance, midpoint, slope, and the y-intercept formula for the line. All you do is type in two coordinates and everything else is done. Anything else?

simple

DISTANCE
prompt A,B,C,D
disp (sqrt((A-C)^2-(B-D)^2))

MIDPOINT
prompt A,B,C,D
disp (A-C)/2-(B-D)/2

Re: Re: Re: Re: Re: Math Program Ideas

another option, with both formulas in one BASIC program for the ti-83+

Prompt L1,L2
Menu( "welcome", "midpoint",MP, "distance", DI, "exit",X)
Lbl MP
DelVar L3
(L1(1)+L2(1))/2 -> L3(1)
(L1(2)+L2(1))/2 -> L3(2)
Disp L3
Stop
Lbl DI
sqrt( (L1(1)-L2(1))^2 + (L1(2)-L2(2))^2) ->D
ClrHome
Output( 1,1,D)
Output( 2,1,"sqrt(")
Output( 2,3,D^2)
Stop
Lbl X
Stop

It may be a bit long, but it gets the job done well.
Note: the spaces are not part of the program

I tried using the program you suggested and all i recieved were errors. It is most likely my fault but there are symbols that are close to the ones you typed that confused me if it isn't too much trouble would you please specify how to type each character. It will most likely will be a pain but would be greatly appreciated
Thank you for your time

the symbols are:
sqrt= the square root button.
L1-L2= list one and list two
^2= is the the number squared.
->= is the sto-> button
if you need it, i could write it for you.
ill email it to you if you need it.

Here it the program I wrote for slope, midpoint, and distance. not that yours wont work, i just think that mine is a little easier to understand for beginners. it is as follows:
:disp "(x,y),(a,b)"
:prompt X,Y,A,B
:B-Y->C
:A-X->D
:if D=0
:then
:disp "NO SLOPE"
:Else
:Disp "SLOPE"
:Disp C/D ->frac
:End
:sqrt(C^2+D^2)->E
:Disp "DISTANCE",E ->frac
:((X+A)/2)->F
:((B+Y)/2)->G
:Disp "MIDPOINT (X,Y)",F,G

Thats all there is to it

Re: Re: Re: Re: Re: Re: Re: Re: Re: Math Program Ideas
chandragupta Account Info

P.S-
->frac displays the anwser as a fraction, it is found under Math:1
also, just so you under stand the program asks for two points, that is the (X,Y),(A,B)
if you type in the point and it displays "NO SLOPE", this is if the line is verticle and the slope involves dividing by zero.

Chill out.

Seriously, don't be a butt.

You say he never assigned R a value, and that you can't just 'store' something ( sqrt(X^2+Y^2)-> )
Using basic problem solving skills, i bet you he meant to say:
sqrt(X^2+Y^2)->R

I know, big leap right?
Anyway, how to TRULY write a slope/midpoint/distance program:

ClrHome
Disp "(A,B) (C,D)
Prompt A,B,C,D
D-B->X
C-A
Disp "DISTANCE",R>Pr(X,Ans
Disp "MIDPOINT", {(C+A)/2,(B+D)/2
If Ans:Then
Disp "SLOPE",X/Ans
Else
"NO SLOPE

That, ladies and gentleman, is the most optimized for memory program you will find.
If you are uncertain what R>Pr is, it is #5 under [2nd][APPS] or the ANGLE menu.

Wait a minute. What's R? You never assigned R a value. And sqrt(X^2+Y^2)->? You can't just store a value. You have to store it into something. Also the "stop" is not needed at all-you hadn't yet used Lbl. Anyway, you don't need to use the Goto function in the first place, and should avoid using it--it's just sloppy coding and can lead to lots of syntax errors in longer programs.

stalepretzel  Account Info

That's correct. Without the stop, it would tell you the slope then inform you that the slope really doesn't exist... also, the goto part is fine... it could be replaced with if then else, but that would be more memory consuming. True, long programs may be confusing with thousands of gotos, but they are generally less efficient if other methods are used.

Sorry, did you say if-then-else is more memory consuming than a lbl statement and a goto statement?

Consider:

:if (C-A)=0
:Goto 1
:(D-B)/(C-A)->
:Disp S->Frac
:Stop
:Lbl 1
:Disp "THE SLOPE IS","UNDEFINED"

//label and goto

:if (C-A)=0
:Then
:(D-B)/(C-A)->
:Disp S->Frac
:Stop
:Else
:Disp "THE SLOPE IS","UNDEFINED"

// if then else.

Dude, all you need to get MP and DI is the same 4 prompts.
So:
::"DIST
:ClrHome
:Prompt X,Y,Z,T
:(Write your own formulas, I have a science fair project I should be working on... Find both DI and MP with them.)
:round(D,5)->D
:round(M,5)->M
:Disp D,M
:Pausde
:End

Gets the job done nicely, not pretty, but efficient. You can even cut out the round func and make a cool
:Output(5,1,"Distance:")
:Output(5,11,D)
:--- Same thing on the next line for Midpoint

Converting to a fraction won't work so well if you take the square root of a number. You won't get a fraction-just an irrational number. Other than that it seems good, once you save a few bytes.

:I'm not saying anyones ideas here are not the best way to go about this program,but i made one without having to input A,B,C,or D more than once. After typing in the X and Y values it will display The distance, and when you press enter it displays the Mid-point, and finally with another press of the enter button it will display the slope as well. (MADE ON TI 84+)

Lbl A
Prompt A,B,C,D

:(B^2+(-4*A*C))->F

Actually, I think you should have

:Disp (-B - Sqrt(B^2-4AC))/(2A

or else you will be adding B to the sqrt of B^2 - 4AC, which will be divided by 2 and multiplied by A.

-2C/(B+{-1,1}sqrt(B^2+4ACi^2-> (L)Q

this gives imaginary solutions too.

My midpoint program is a little more friendly, but performs essentially the same functions as those listed above:
:Prompt W,X,Y,Z
:((W+X)/2)->A
:((Y+Z)/2)->B
:Disp "X IS",A
:Disp "Y IS",B

...and that's it.

you might want to use output instead of disp if you want it to be user friendly-it looks better if everything's lined up on the left.

Be nice everybody. Not everyone's a TIGC junkie. I would like to take the opportunity to say that if any you hardcore B.A.S.I.C want to make some easy $40-$120, make a algebra solver that does everything from slope to solving systems of quadratic inequalities, put it in a group, and see if it's under 8,000 RAM... It took me 'bout 4 months, but it seriously paid off!!!

slope1.5 Account Info

I made a program called slope15 that is the ultimate xy plane line/point analyzer. It first asks you to input a line in one of three forms: two points, slope/point form, or standard form. It then gives lots of info about the line, I.E. slope midpoint, length, distance from intercepts, intercept location, etc.. Then you can chose from a set of functions. You can make a new line and compare it to the first (parallel, perpindicular, bisectors, etc.). You can input a point and it will tell you it's location in relation to the first line. You can find X(Y) or Y(X). Many other things can be done with combinations of the functions. I don't currently have a link cable but I will post it when I do.

These two programs together will give you exactly what you are asking for. The second one, "DISMID" calls on the first one, "DISTANCE", and releys on the fact that it leaves the cooridnates in the calculator's memory as A, B, C, and D. Make sure to name the first program "DISTANCE" in you calculator or it will not work.

Enjoy.

DISTANCE

Disp "POINT 1 X"
Input A
Disp "POINT 1 Y"
Input B
Disp "POINT 2 X"
Input C
Disp "POINT 2 Y"
Input D

Disp "DISTANCE IS:"
((A+C)^2+(B+D)^2)üE
Disp E

DISMID

prgmDISTANCE
Disp "MIDPOINT X IS:"
(A+C)/2üF:Disp F:Disp "MIDPOINT Y IS:"

Math Program Ideas: Midpoint and Distance Formula
[UAC]Felix Account Info
(Web Page)

You are in luck! I have just made a Prgm recently that calculates the midpoint of point A(X1,Y1) and point B(X2,Y2),their midpoint, and most difficult: the location of point B(X2,Y2) given point A's location and the Midpoint. I should have it on my gaming clan's url shortly, as soon as I manage to debug the program. For now, I can give you the essentials:

The distance is the number of units between two points, as you know.
To find the distance, it is best you have a calculator;
BECAUSE MY COMPUTER DOESNT HAVE THE NEEDED CHARACTERS, I WILL USE WORDS!
vAv vBv
d=the square root of((X1-Y1)^2+(X2-Y2)^2)

If you wish, you can make the program yourself by doing something like:
:ClrHome
:Input "X1=",S
:Input "Y1=",D
:Input "X2=",F
:Input "Y2=",G
:[Enter the formula given above]
:Ans

The midpoint finder is on my calculator, which I left in my locker... Check my site soon and often!

Personally, I use this on my 89. Two separate functions, quite easy to use and/or adapt for other calcs.

Midpoint:
m(x,y,z,t)
Func
({x,y}+{z,t})/2
EndFunc

Distance:
d(x,y,z,t)
Func
?((z-x)^2+(t-y)^2)
EndFunc

I like a simple approach.

Here's a way to get slope, y-intercept, midpoint, and distance at the same time. It is kind of lengthy, but works great with a great interface (unless the numbers are huge).

:ClrHome
:Input "X1:",A
:Input "Y1:",B
:Input "X2:",C
:Input "Y2:",D
:Disp " "," ","
:(V-X)^2+(W-Y)^2->A
:If V=X
:Then
:Output(3,7,"None
:Output(4,7,"None
:1->N
:Goto N
:End
:(W-Y)/(V-X)->B
:Y-B*X->C
:Output(4,7,C
:Lbl N
:Output(1,1,"X1=
:Output(1,4,V
:Output(1,9,"Y1=
:Output(1,12,W
:Output(2,1,"X2=
:Output(2,4,X
:Output(2,9,"Y2=
:Output(2,12,Y
:Output(3,1,"Slope:
:If N/=1
:Output(3,7,B
:Output(4,1,"y-int:
:Output(5,1,"Midpt:X=
:Output(5,9,(X+V)/2
:Output(5,12,"Y=
:Output(6,1,"Dist:
:If int(&#8730;(A))=&#8730;(A
:Then
:Output(6,6,&#8730;(A
:Else
:Output(6,6,"&#8730;(
:Output(6,7,A
:Output(7,6,&#8730;(A
:End

&#8730; is the square root sign
-> is the store function
^2 is the squared function

Can someone show the correct formula(r?) for solving systems of quadratic inequalities please? I wrote one before that only worked for about 20% of the equations I fed it. I've been prgming for 2 years in BASIC now, so I know I didn't have any syntactical errors in it. I have no clue why it wouldn't work at all at times. The graphing and table parts came out, but with the wrong equations totally... I know this screams twisted code but I've had my dad and brother pick out the code and except for the formula part they couldn't pick out anything wrong with it.
Oh, and please don't tell me to Google it, that's what I used to find the formula before and besides I think that math forums run by certain unnamed parties are massively unreliable.

Hi, I'm studying Trigonometry in my geometry class, and I was wondering if there was a program you can code to solve matrices when finding the coordinates of points rotated by theta degrees around the origin.
Example:
[cos(theta) -sin(theta)] [0 1 5]
[sin(theta) cos(theta)] [0 4 2]
Only as two matrices, one being 2x2 and the other 2x6

I figure you would need to prompt for theta, and the x and y coordinates of the points in the second matrix, but I'm not sure what to do from there....
Help is very much appreciated!

Hello all, I have a TI-83+ and need some help with a program I am making.

I have a program that draws a circle with circledraw(0,0,1).

I want to be able to calculate calculate the points on the circle when the angle is 30*, 45*, 60*, 90*, 120*, 135*, 150*, 180*, etc..

The catch is that I need the points to be in simplest radical form (not floats). Any idea on how I would go about doing this?

I know that I use sine and cosine to calculate the points. for example:

coordinates for 60*

ClrHome
Degree
Input "Enter angle: ", I //Enter 60 here
cos(I) -> X
sin(I) -> Y
Output(3,1,"(")
Output(3,2,X)
Output(3,5,",")
Output(3,6,Y)
Output(3,9,")")
Stop
Radian
End

...but I don't know how to put them in simplest radical form.

Home or drawing screen can be used to display the points, I have no preference. Thanks!
