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!
Nexus 7 (2013)
Please note, people with SGS4's have been reporting crashing. I'll take a look into it as soon as I can!
• 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:
• solve any triangle, not just right angled
• set the number of decimal places that answers are given in
• enter angle values in fractional pi radians, degrees or decimal radians, or a combination
This app has no ads. The in-app purchase is entirely optional, it's not forced upon you. There's a button in the Settings and Info screens that will initiate the in-app purchase window.

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.
Test your ability and practice the angle functions in a smart intuitive way.
• Visual method
• Specific functions values training (sine, cosine, tangent)
• Angle values in radians training
• Learn functions' values figuring out the unit circle (Best method)
