At its most basic level, Trig Touch calculates triangles.

But this makes Trig Touch a very versatile app.

You can use Trig Touch to:
-Manipulate vectors (go between components and magnitude/direction)
-See the trigonometric functions with graphics and animations
-Find parts of triangles without having to go through all the math
-Answer questions intuitively (what is the length, width, and area of my devices screen? I know the diagonal dimension and the aspect ratio.)

Trig Touch features intuitive input manipulation with gestures, fluid animations between triangles, a helpful series of tutorial images, an animated demo, and a written section describing the calculations that Trig Touch performs to complete the triangles.

Whether youre an engineer working with vectors and making geometric designs, or a student learning trigonometry for the first time, Trig Touch is a useful app that will make your work easier.

And its free! You have nothing to lose except disk space.
