Cercle trigonométrique

The application provides one or two indices characterizing an angle (for example, its sine and the sign of its cosine). The user must find all the other data relating to this angle: measure in degree, measure in radian, sine, cosine, tangent, quadrant, radius on a trigonometric circle.
After validation, the application provides all this data, rewards the correct answers, and penalizes the false or missing answers. The user can then obtain a new random proposition (among the following angles: 0 °, 30 °, 45 °, 60 °, 90 °, 120 °, 135 °, 150 °, 180 ° and their opposites).
It is a question of obtaining a maximum of points in a minimum of time.
A "Reading" mode displays the properties of each remarkable angle.
Users can share their performance.
A trigonometry form is available for consultation.
