The best I had just downloaded 6 trigonometry apps in last 2 minutes, and this is by far the best. Unlike the others, yes, they're complete, this one is well organized and contains the basics that WILL end up in my exam... great!

Anurag Jain

Nice app for me and i think every body should get this I think you should add a sum solver for trigonometry. So that any doubt in trigo sums can be solved....

A Google User

Great for trig students! This will really help you get through trig in high school. With this app, I feel like trig is now easier. Everything you could ever need for trig is in this app.

## Trigonometric Formulas

This is suitable for all students, teachers and practising engineers.

This app has gentle introduction with large number of diagrams and graphs for deeper appreciation of trigonometric concepts.

Most useful formulas are included with relevant diagrams. The formulas help in solving and proving trigonometric equations.

Radians are introduced early. Trigonometric function values for commonly encountered angles provided with diagrams.

Angle reflections with respect to X Axis and Y axis are dealt with in detail. Graphs are used for clarifying the rotation and reflection formulas.

Circumscribed and inscribed circles formulas explained with diagrams.

Different formulas for computing area of triangle are provided.

Series expansion for trigonometric functions provided.

This app can be used with mobiles phones and tablets of all sizes.

Inverse Trigonometric functions are dealt with in great detail.

## 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;
