This program will give you 4 values in positive degrees for the angle and those values in radians. After you solve a trigonometric equation, you can use this program to find several values of the angle using tan( and cos( as well as sin(. After solving for the values, you can use the extraneous solution finder to see if any of the values are extraneous solutions. |

| **amazingtrigvalues.zip** | 1k | 12-04-27 | | **Amazing Trig Values** Have you ever gone to math class, typed in sin(some number), and all it shows is a decimal rounded to nine places? This program displays the sin,cosine,and tangent of a value as they really are. (for example instead of 1.7320508, it just says the square root of 3) Useful for Geometry, Trig, and Precalculus students. New in this version: can recognize common inverse sin/cos/tan values, and convert them to multiples of pi. (It's bigger, so the old version is also included.) |

| **ampperiodp.zip** | 1k | 04-02-18 | | **Amplitude,Period,Phase Shift** Input the Amp, Period, and Phase Shift and it will output the equation. |

| **atriangle.zip** | 1k | 04-02-17 | | **Dan's Triangle Solver** This is a simple but effective program that find the missing angles and sides of a triangle |

| **atrig1.zip** | 1k | 04-03-07 | | **ATRIG** ATRIG is a program to find those exact values, from the ANS-memory, in trigonometric functions. Like one over squareroot of two, squareroot of three and the others. It also gives you all the multiples of pi, for a denominator of onto 10,000, in a second! The result is shown with the Text(-command, wich means that the built in >Frac can't be used. At 215 bytes it's unique! |

| **atrig2.zip** | 1k | 12-06-17 | | **TRIGVALUES** This program finds the exact values in trigonometric functions, like square root 2 over 2, square root 3 over 3, and so on. The program does not change your mode. If you enter a value like 60 or pi/3, the program, regardless of what mode you are in, gives you the exact values for sine, cosine, and tangent, assuming that 60 is degrees and pi/3 is radians. If you enter sin(45 in mode degree, or sin(pi/4 in mode radian, the program will give you the values for the inverse sin/cos/tan in terms of degrees or radians/pi, depending of what mode you have. You can of course also enter values like sqrt(3)/2 or inverse sin(sqrt(3)/2. If you want to examine a value that is in the Ans-memory, just press X when you are asked: "VALUE?". UPDATE: The program now shows the input on the result screen, if that differs from the value on top. |

| **atrig3.zip** | 1k | 01-05-01 | | **ATRIG v3.0** This is the last in the series of ATRIG programs. This is basically the same as previous versions, except it is much more advanced. It gives you the choice of which trig function you would like to see the values for. Thank you for contributing to the great success of this series. |

| **atrig4.zip** | 1k | 10-04-20 | | **Exact Trig Values-A Table** This program contains a table on the 13 exact trigonometric values, with the corresponding angles for sine, cosine, and tangent, in degrees and radians, plus the angles for tangent where it's undefined. You can toggle up and down in it by pressing the arrow keys: arrow up for up, arrow down ( or any other key than up or ON ) for down. Look at the screenshots. |

| **atrig5.zip** | 1k | 10-04-29 | | **Trig Values Reverse** This program is the reverse of the usual program of this kind. Instead of giving it angles and get the exact values, you give it the exact values and get the angles. The 13 exact values: 0, + -1, + -1/2, + -sqrt(2)/2, + -sqrt(3)/2, + -sqrt(3)/3, and + -sqrt(3), are displayed on the screen for your choice. When you make a choice it gives you the angles for sine, cosine, and tangent, but not just one angle each: For example -sqrt(3)/2, gives you the angles -60 and 240 for sine, and 150 and -150 for cosine, in mode degree. In mode radian that value gives you -pi/3 and 4pi/3 for sine, and 5pi/6 and -5pi/6 for cosine. For tangent the period of N*pi, or N*180 is given when the angle gets an exact value. The program works without changing any mode you have set, but to use it fully you need to alternate between mode degree and mode radian. |

| **atrig6.zip** | 3k | 11-03-17 | | **Trigonometric Solvers** ATRIG8: This program solves trigonometric equations like sin(2X)=cos(3X), tan(X)=√3, and all the other combinations you can think of. Just remember to use X for the variable. It has a built in safety check, so it skips values that are not defined, instead of giving you an ERR: DOMAIN. You do not have to give it angles to search within, or number of solutions you want. It simply searches 0 to 360 degrees with a precision that you choose. If you choose 5, for example, the program will check every fifth degree from 0 to 360. Look at the screenshots. ATRIG9: This program is the same as the one above, except that it searches angles that are E-3 off from an integer, so that it won't give you an ERR: DOMAIN. When the equation is close to a match, it puts the value of X, rounded to two, into list 1, wich is displayed when finished. ATRIG0: This program searches for the precision by itself. You just have to give it the equation with X as variable. There is only integer values for the angles though. Might be the the right program for you if you are uncertain about the precision. ATRIG10: A coventional program, described in the textfile. ATRIG11: This is the same as ATRIG0, exept that it can also handle a precision of half a degree. For example: sin(X)=cos(25.5). |

| **atrig7.zip** | 8k | 11-07-08 | | **ATRIG12** This program solves trigonometric equations of the type: tan(3X)=0.8, sin(2X)=0.5, or cos(4X)=1/sqrt(2). It's a complement to the programs in atrig6.zip, since those programs have trouble solving, or can't solve an equation of this type. |

| **atrigga.zip** | 2k | 01-04-04 | | **Atrigga** Solves any triangle given a side and two other pieces of information, and even solves ambiguous SSA triangles. It also shows the area and perimeter and allows you to visualize the information graphically. This is the BEST TRIGONOMETRY PROGRAM ever seen on a TI-83. |

| **atrighelper.zip** | 1k | 05-11-02 | | **Trig Functions Helper** This programs works by using the basic trig function y=a*trig(bx-c)+k, where "trig" can be sin, cos, tan, csc, sec or cot. After entering the requested values, it solves for: amplitude, period, scale, reflection, vertical stretch/shrink, horizontal stretch/shrink, phase shift and vertical shift. It's a very nice program, so at least check out the screenshots (please). |

Also created a block for unknown angles. -Instead of displaying all of the angles and sides upon completion, program now only displays the unknown side that you requested to save time and space. ----------End Update---------- Input the values for two angles and two corresponding sides of any triangle. For unknown values, input a 'zero.' The program will then use the Law of Sines to find the values for the unknowns you entered.

| **righttrianglesolver2.zip** | 20k | 09-11-14 | | **Right Triangle Solver** This program calculates answers for right triangles, given two pieces of information. It uses the getKey function to store user input into a string, one number at a time, and displays it on the graph screen as the user enters it, one number at a timeuntil the enter key is pressed. However, I dont check for all user errors, such as entering a degree larger than 90. This program displays a menu at the bottom of the screen, with a prompt directly above the menu options. There are as many as five menu options to choose from at any one time. These menu options correspond to the first row of keys at the top of the calculator: Y=, WINDOW, ZOOM, TRACE, GRAPH. These keys are used to select the menu option desired by the user. Above the prompt, a right triangle is drawn, with angle labels, and then side labels. When selected, the angle or length can be entered adjacent to where the angle or side is located. This allows the user to see that he is indeed putting the known information in the correct location. The left arrow key can also be used to backspace. For the record, this program requires a companion program, ZINPUTST, which is explained in comments below, and in another Word document in the ZIP file. This version times out after 1 minute to save your batteries. |

| **trix.zip** | 1k | 03-03-07 | | **Triangle Solver** This program is forthright and easy to use. Coming in just under 2 KB, this program uses one mere variable X (no lists) to solve any triangle using the Law of Sines and the Law of Cosines, where one side and any other two parts of the triangle are inputted, even displaying all possible solutions in the case of an ambiguous case. Additionally, this program checks to see if such a triangle actually exists in the first place. Try this program, and I promise you won't be disappointed. |
