Cercle trigonométrique

"Cercle trigonométrique" is an engaging Android app designed to enhance your understanding of trigonometric concepts. Users receive one or two indices of an angle and must determine additional related data, such as its measure in degrees and radians, sine, cosine, tangent, quadrant, and the corresponding radius on a trigonometric circle. After validation, correct answers are rewarded, while incorrect responses are penalized. The app also features a 'Reading' mode, performance sharing, and a trigonometry reference form.
