TITrig

Triangle solver for the TI-84 Plus CE

Note: this code is extremely inefficient and a rewrite is warranted. You should also be careful when inputting data as illegal characters may cause an access violation.

Features

TITrig can solve for any type of triangle, right or non-right.

Non-right triangles

• Displays any extraneous angles
• Automatically detects the type of triangle (i.e. SSS, SAS, etc.) and displays it
• Automatically solves for the third angle when possible
• Automatically calculates the area and perimeter
• Automatically solves for the triangle when possible

Right triangles

• Automatically solves for the missing side (pythagorean theorem)
• Automatically solves for the third angle when possible
• Automatically solves for 45-45-90 and 30-60-90 triangles
• Displays all trigonometric ratios (sin, cos, tan, cot, csc, sec)
• Can display the trigonometric ratios in either plain fractions (decimals) or as simplified radicals
• Displays the simplified radical form of a decimal when a decimal is selected
• Features adjustable rounding (0-9 digits) which can be turned off
• Supports inputting inline square roots

Example
