Wasn't what I was looking for, but it's AD free AND requires no special permissions, so I gave this 5 stars. Good job.

Larry Feldman has developed the most robust, well-defined math apps on the market. Choose your subject, and Larry probably has an app for it. For the math student interested in an all-inclusive app, Math Pro by Larry Feldman is superior to all other apps on the market. Learn through his notes, test your answers with his calculator. He's done it all. I am a former calculus instructor; and my professional opinion, Larry's apps are engineered for learning. And learn you will.

Great app. Easy to use.

This app is a huge help to me, but I think it would be even more useful if it gave the steps taken to solve the problem.

These are my first comments. I found this reference app very very good, and I will be using it with my students. One comment tought. I teach trigonometry using the Unit Circle fully (to calculate the six functions and their inverse, as well as identities, etc). This is the first Android app I have seen that showed the six trigonometric functions on the Unit Circle (congratulation), although non interactive. I found just one small trouble: the Csc/Cot graph: it is hard to infer the triangle formed even when the side "1" is explicit, unless it is drawn upside down. The cotangent line is the horizontal tangent intersecting (0,1), from the work of the arab astronomers such as Abu Al-Wafa (980 c.e.). A green line profile can then be drawn representing the one on the app to illustrate its equivalency. Interactivity will make this part of the tutorial Excellent.

About this app

Raise your hand if you think the only solutions to sin(x) = 0.5 are 30 degrees or pi/6 radians. Feel free to use your calculator.

If you raised your hand, promptly use your hand to download this application.

There are actually an infinite number of solutions to most inverse trigonometry problems, but your calculator probably only gave you one. Guess what. Your teacher probably wants you to explain all of the solutions. "Trig Pro" does that.

This unique app also computes the reference angle in degrees or radians for any given angle. Useful in real life for most people? No. Useful for Trig students? Definitely.

"Trig Pro" contains a wealth of solvers and tutorials:

- A unit circle in vivid colors
- Unit circle representations of the six trig functions
- A triangle solver (SSS, SAS, AAS, ASA, SSA)
- A solver for showing attributes and graphical representations of the six trig functions
- Changes in amplitude, period, horizontal shifts and vertical shifts
- An extensive list of formulas and identities
- Degree/Radian converters
- Tutorials on 30-60-90 and 45-45-90 triangles
- Step-by-step examples of solving inverse trig problems
- Step-by-step examples of simplifying trig expressions
- Angles of Elevation and Depression
- Polar curves: Limacons, Rose Curves, and Lemniscates

New features

Had to change the keyboard to alpha-numeric because some devices don't show a decimal point or negative sign otherwise. Believe me, I'm not happy about it either.
