KnowYourAngles is designed to help students in Trigonometry learn the values of the Unit Circle. It selects a random problem and displays it. The user writes their answer in the given space. The answer is made beautiful using MyScript's Interactive Ink SDK 1.3, and the result can be used to check if the user's answer is correct.
