Trig Inverse Function Practice app for iPhone and iPad

An app that only teachers and students of Trigonometry will appreciate.

This app focuses on the common inverse Trigonometry for Sin, Cos and Tan only.

For teachers, allows them to easily generate random trig inverse function questions with 1 correct answer and 4 other random, yet possible answers. Each question can be based upon Degrees or Radians which is easily selected via buttons.

For students, provides self-paced practice for memorizing the trig inverse functions. The app provides for 4 timing modes including untimed (the default) , 1, 2 and 5 minute testing modes. Like the teacher, the student can easily select questions and answers via Degrees or Radians. After the student has answered a question, the app give them immediate feedback including the correct answer if they choose the wrong answer. In all modes, the total number of question requested and the number answered correctly is displayed at the top of the screen.
