thx a lots!!but need a little correction on (+/-)..i'm agree with marten,dave& true.. that's a fatal error!! please fix it for us all.TQ

A Google User

Its confusing, I do it better with my mind. Nothing extraordinary. Good to ppl struggling with trig though

A Google User

Bionic usa I like but on high res device you need magnifying glass

A Google User

Nice App for the Trig challenged like me. Droid Eris.

Awesome Had to learn trig for a new job. This was amazingly helpful.

Awesome Had to learn trig for a new job. This was amazingly helpful.

Simple & Effective Concise info on a dark background. Thx Nexus 1

Dumb thought it would explain trig properties does nothing of the sort.

When you set the angle the wrong angle is shown. Eg. 90 ° is shown as 270°

Um... counter-clockwise produces a positive θ/degree growth. You have it backwards. You may want to fix that huge error...

Would be 5* if value of circle could be changed from 1 to any number

Value of (0,-1) is located at top of circle? Kind of a major error

Sorta odd that the circle is top side down. And I wish it could do rad as fractions of pi.

This app is amazing it makes my freshman year easy and helps me understand trigonometry concepts

Would be nice to be able to enter an angle, including decimal values and ° ' ". Occasionally force closes. Droid X.

Got a little better. Now can do anything under one inch. Can you add trackball support to move the sliders trying to hit .3574 with your finger is imp

This should help This should help for college. But the menu needs upgraded. I click 'other', and it freezes. But I'll like it.

This free math app is a collection of the most important trigonometric formulas for sine, cosine, tangent and cotangent. It shows you:

- 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.

Trigonometry Calculator is a mathematical program through which, put 2 values (2 sides, 1 side and 1 angle, area and 1 side,area and 1 angle, perimeter and 1 side, perimeter and 1 angle), calculates the remaining unknowns of the right triangle. The program is in Italian and English language and is very convenient for both students and workers who use trigonometry such as operators of CNC machine tools. There is also a table which lists all the mathematical formulas to learn the fundamentals on trigonometry (the text is in Italian only). The program, unlike others of its kind, not only is complete but is also free.

## Unit Circle (Trigonometric)

The unit circle or trigonometric circle is a circle whose center is located at the origin of the Cartesian plane and its radius is 1 (one). It is used in the study of trigonometric functions such as sine, cosine and tangent.

- 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;
