- 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;

Please note, people with SGS4's have been reporting crashing. I'll take a look into it as soon as I can!
- symmetry laws
- shifts laws
- periodicity laws
- angle sum and difference identities
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.
master trigonometric function computations includes
practice mode as well as trigonometric function calculator
useful for students learning pre-calculus mathematics in
school and college. All steps shown when computing sine,
cosine, tangent, secant, cosecant, and cotangent ratios
for various angles for the most common right triangles
which are taught in school. Both degree angles and radian
angles available. Good teaching and study aid for
mathematics, practice for quizzes, tests, and exams
in a fun and easy to learn way with Easy Trig.
1. List of formula group.
2. Next and previous key to change formula group.
3. Easy readable format of formulas.
4. Tables for derivative and Integration.
The arguments covered vary from the graphical representation of functions (sin, cos ..), domains, codomain, roots etc etc.
This application will allow you to have somethings about Trigonometry always with you , to clear doubts and in preparation for tests or exams.
The application does NOT require data connection NOR specific readers.
Test your ability and practice the angle functions in a smart intuitive way.

So What is the Unit Circle?
The Unit Circle in mathematics is a circle with a radius of one, with the origin located at (0,0). The Unit Circle is usually used near the end of the High School math curriculum. While the Unit Circle is used to introduce kids into trigonometry it is an essential skill that needs to be learned. For the most part the Unit Circle can be learned from memorization, but the deeper in you go the more complex the Unit Circle becomes. Use this app to help learn and discover parts of the Unit Circle.
(Unit Circle supports full 1080p resolutions)
