Math.Trig is an easy-to-use free app built for the iPhone, iPad and iPod touch, which solves triangle problems. Watch a demo video by clicking on the play button at the bottom of the iPhone screen to the right.
This is how the app works:
Simply draw a triangle straight on to the screen. You can even choose the color!
Or input particular values. You can select, degrees, π radians or gradients.
Find out how Math.Trig calculated the results on the explanation page. You can even email yourself the results, very helpful for your homework!
You can save your triangle and results for later. Also take a look at the preloaded special types of triangle.
For an in-depth look at Math.Trig, visit our screen by screen walkthrough.
If you want to know the math behind finding angles, sides and areas of a triangle, then take a look here.
From Pythagoras' Theorem and basic trigonometry to the Laws of Sine, all you need to know to solve every triangle!
"I'm always a bit reluctant to let my children use a calculator instead of using their heads, so I was pleased to see this app has a section showing the trig formulas behind the solution!"
