- 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.
If you get any error or problem running the app. Send me the report and some message. So I get more information about your android version, screen size, ... so I can fix it. Thanks.
This App has all the important formulas and concepts
-Inverse trig functions
-Law of sine and cosine
-Negative angle formulas

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.

Excellent Excellent work
Excellent Great work it is helpful app
Easy geom Was a great app but stopped working so cannot use it
Awesome! Just what I needed!
Thank you for your response
• solve right angle triangles
• let you enter angle values in either degrees or radians, or a combination
• convert angle answers between degrees and radians
• solve for area
For $1 you can unlock the Pro features as an in-app purchase
Pro features include:
