Application provides one or two clues characterizing an angle (for example, its sine and the sign of its cosine). The user must find all other data related to this angle: degree measurement, radian measurement, sine, cosine, tangent, quadrant, radius on a trigonometric circle.
After validation, the application provides all this data, rewards the right answers, and penalizes false or missing answers. The user can then obtain a new random proposal (from 0°, 30°, 45°, 60°, 90°, 120°, 135°, 150°, 180° and their opposites).
The aim is to obtain a maximum of points in a minimum of time.
A memo about Trigonometry can be consulted.
