Find mistake or did not find what you were looking. - please send us e-mail.
- Understand how the projections of the arcs sine, cosine and tangent work in the unit circle (or trigonometric circle);
- Why the values of sine and cosine are limited to -1 and +1;
- Why the tangent of 90 ° and 270 ° are not defined
- When and where the values of the trigonometric ratios (sine, cosine, tangent) are positive, negative, zero or null;
If you have any suggestion fell free to contact me.

Best math tool for school and college! If you are a student, it will helps you to learn geometry!
Note: Trigonometric functions are used for computing unknown lengths and angles in triangles (in navigation, engineering and physics). The sine and cosine functions are also commonly used to model periodic function phenomena such as sound and light waves, the position and velocity of harmonic oscillators.
This is the same app as the Unit Circle Quiz (https://play.google.com/store/apps/details?id=com.chrisk.UnitCircleQuiz), with the addition of ads. All features present in the paid app are present in this one!
