CalcApps' Math iPhone and iPad Apps

At the moment we have one math app available from iTunes and the App Store, Math.Trig. It is built for the iPad, iPhone and iPod touch.

Math.Trig

Math.Trig is a triangle solving calculator, the only one we know of, where you can draw a triangle straight on to the screen. It also has an explanation page so you know how Math.Trig solved the problem, helping you to learn trigonometry!

Find out more about this free app in our overview with screenshots or see our in depth page-by-page walkthrough.

What's a Triangle Solving App?

Very simply it calculates missing angles or lengths of a triangle. You input the values you know, like an angle and two side lengths, and the calculator will work out the rest using the rules of trigonometry.

Why do I need to solve triangle problems?

Students of math, need to be able to use trigonometric functions to solve many geometry problems, knowing the basics of triangle geometry is a good place to start.

In the real world triangles are everywhere, in structures such as roof rafters, bridges, buildings, like the Louvre Pyramid, and even stealth fighter wings! All these have to be designed and the measurements accurately calculated by finding the dimensions of a triangle.

Triangulation is also used to locate the center of a point, your iPhone uses triangulation to verify its position when GPS is not available!
