Description

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 gives 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

Really useful app that has loads of tools to help with trig. I think that the solvers are the best things… instead of having to do calculations on the calculator you can just put in the numbers for the topics and it gives you the answers in one step. Great to save a bit of time.

Thank you for developing this app for those students who need help in studying for the tough course of Trigonometry. It's nice to have an app that covers some of the basic and more challenging concepts of trig, from angles of elevation and depression to inverse operations and more, and it includes examples of how to simplify some of the most used trig functions. Worth the download price!

Incompatible

Rssfees

I bought this app and used it for a while and apple came our with their worthless 3.1.3 update and now I can't use it because I don't want to update. I really could care less if my Japanese keyboard is working so I'm waiting for 4.0 firmware. In the meanwhile I am locked out of an app that I spent my hard earned money on because the bew update is incompatible with my current firmware. This isn't the first prblem I've had with this waste of money. Don't buy it.
