http://www.ticalc.org/archives/files/fileinfo/469/46970.html
Banchor is a huge Zelda-type RPG for the TI-84+CE! You take control of the heroic Rex, as he ventures on a mammoth quest to rescue the kidnapped Princess Sapphira and defeat the evil demon from Hell, Banchor. Upgrade your weapons and defenses, increase your life level and meet many people along that way that will help you in your quest!Fri, 13 Oct 2017 21:29:19 GMTTI-83 Plus/TI-84 PlusALGEBRA 1-2
http://www.ticalc.org/archives/files/fileinfo/469/46971.html
This program has seven programs for algebra: Quadratic equation, distance, midpoint, slope, tri distance, pythagorean, and polynomial factoring. 3655 bytes. Thorough description in the text file.Tue, 10 Oct 2017 19:56:01 GMTTI-83 Plus/TI-84 PlusTI-PLOW: A Seasonal Game
http://www.ticalc.org/archives/files/fileinfo/466/46623.html
Help Timmy the plow truck driver plow all the snow in the city. However, due to budget cuts, Timmy will lose his job if he drives the plow over areas that don't have any snow: that would waste fuel, time, and money. Try not to take too long, the city doesn't pay overtime.Tue, 10 Oct 2017 19:55:42 GMTTI-83 Plus/TI-84 PlusFACTOR
http://www.ticalc.org/archives/files/fileinfo/423/42305.html
This program finds the linear factors of a polynomial of one variable. Try for example 117X^4 -20X^3 -390X^2 +20X +273. If the polynomial only has rational factors it will be completely factored. The above example will factor as (X-1)(X+1)(9X+13)(13X-21), If the polynomial has irrational or imaginary/complex roots in addition to rational roots, or if the program can't find any factor, the program will show the coefficients of the remaining polynomial. For example: X^3 +X^2 +X -3, will give a linear factor of (X-1), the program will then display: OTHER FACTOR: {1 2 3}. Which means that 1X^2 +2X +3, is another integral factor. If the program can't find any linear factor, or when there is not enough of them, it tries a substitution for X^2. It can then find factors like, (AX^2+B). This makes it more likely that it finds all the integral factors. Try for example: X^5-X^4+2X^3-2X^2-15X+15. UPDATE: The program is now three times faster for the first equation above.Tue, 10 Oct 2017 19:49:49 GMTTI-83 Plus/TI-84 PlusFACTOR8
http://www.ticalc.org/archives/files/fileinfo/458/45817.html
UPDATE: This is a more comprehensive version of the program: It now solves real rational polynomials with rational real and imaginary roots. Just as before, it can make a substitution, X^N. It can therefore find roots like: ( 2X^3 - 3), or ( 3X^4 - 5i ). If there is something left over of the polynomial, it is texted out on the graph screen, not as before given as a list of coefficients. It has 1878 bytes, which is really small, considering what it can do. This includes a bug fix.Tue, 10 Oct 2017 19:49:44 GMTTI-83 Plus/TI-84 PlusFactoring Trinomials
http://www.ticalc.org/archives/files/fileinfo/425/42575.html
ADDMULT: This program asks for two numbers A and B, then finds two numbers C and D, that add up to A and multiply to B, so that A=C+D, and B=C*D, if that is possible. If not, the program gives you a "FAILED". This is for factoring trinomials. ADDMULT1: This program assumes that the trinomial you are trying to factor is a quadratic equation on the form: AX^2+BX+C=0, so if it can't find two integers that add up to A and multiply to B, it solves it by giving you two irrational or two complex numbers.The program always asks for A. ADDMULT2: This program is less complicated to use. It asks you for two numbers A, and B, and then finds the two numbers C, and D, that add up to A, and multiply to B, wether C or D are real integers or irrational/complex numbers. ADDMULT3: This program is aimed for the general problem. It asks you for the degree of the first term, then for its coefficient, the degree of the second term, and its coefficient, then for the last term. If the "roots" are real and rational it factors them for you. But it can also handle complex numbers if they are rational. I would like some feedback on these programs. Please let me know what you think of them!Tue, 10 Oct 2017 19:49:29 GMTTI-84 Plus CSE/CE BASICVector Math
http://www.ticalc.org/archives/files/fileinfo/469/46969.html
This program uses wither 2- or 3-dimentional vectors entered in rectangular or polar, cylindrical or spherical coordinates. (All vectors must be converted to rectangular for computations.) You can enter one or two vectors and in degrees or radians. For single vectors you can 1) convert between rectangular and polar coordinates, 2) find the unit vector, 3) compute the norm (length), and 4) find the direction cosines. For two vectors, you can 1) add or subtract them, 2) compute the dot product, 3) the cross product, 4) the angle between vectors, 5) the component of A on B, and 6) distance of a point to a line.Tue, 10 Oct 2017 19:51:36 GMTTI-84 Plus CSE/CE BASICFACTOR

http://www.ticalc.org/archives/files/fileinfo/469/46968.html
A squad car (P) persues a car of criminals (E) on a infinite checkerboard. P moves with velocity of 2 squares per move, but it may only keep its actual direction or turn right. E moves with a velocity of 1 square per move, but may take each of the four orthogonal directions. P wins the game if it comes within a distance of 1 square to E (also diagonally), E wins if it can avoid that for 50 moves.Tue, 10 Oct 2017 19:51:09 GMTTI-83 Plus/TI-84 PlusAngle of View
http://www.ticalc.org/archives/files/fileinfo/469/46957.html
ANGLE2: Do you have a camera and want to know its angle of view? Or do you just want to know what a specific angle looks like. Then this is a program for you. First you choose whether to enter values for the formula: 2*arctan(sensor size /(2*focal length))= angle of view, or if you want to enter the angle right away. By sensor size is ment the horizontal size of the sensor in mm, if you want to know the horizontal angle. If you want to know the diagonal angle you enter square root of the horizontal side to the power of two, plus the diagonal side to the power of two. ( sqr( s1^2 + s2^2) Pythagoras formula ). Then you enter the focal length in mm. The program then draws a circle sector with that angle. ANGLE3: This program can take several sets of values. It uses a list to host them. After youÃ¢ÂÂve entered them the program draws up the data one by one on the screen. OPTICS: This program lets you choose an unknown from focal length: F, size of sensor: S, or angle: A. There are three formulas in it, one for each constant.Wed, 27 Sep 2017 18:26:20 GMTTI-84 Plus CSE/CE BASICAngle of View

http://www.ticalc.org/archives/files/fileinfo/469/46966.html
A betting game you can play against your calc. The calc generates n positive random numbers, 3<=n<=10, and discloses them one by one. You say "stop" (press F3) as soon as you think the last number disclosed is the largest of the whole sequence. You win if you are right, otherwise the calc wins.Fri, 22 Sep 2017 17:30:23 GMTTI-83 Plus/TI-84 PlusSudoku helper 2

http://www.ticalc.org/archives/files/fileinfo/469/46963.html
This program calculates big numbers which are accomplished with either exponentiation, multiplication, division, addition, or subtraction. For example: 789^5, 12345678901234567890/123, 147852369147852369-123456789012345, 12345678901234567890+12345678901234567890, 475896123617*963258741236. The operations are entirely list based, so you can get up to 999 digits. Should the result of an operation become negative, only the first digit in the resulting list is negative: For example, 191-888=-697, and the answer comes out as, {-6 9 7}. This is to be seen as: -600-90-7, NOT as, -600+90+7, i.e. all the digits are to be seen as negative, if the first one is so. The program also gives the sum of the digits in the resulting list.Mon, 18 Sep 2017 18:02:13 GMTTI-NspireFoundation with Failing Tension Zone v1.03
