Makes solving right-angled triangles easy!
Trigonometry help is a simple, yet robust, triangle calculator that enables you to quickly and easily find unknown angles & sides of any right-angled triangle.
Once you've found the unknown values, Trig. help can draw a scale drawing of your triangle, so you can get a sense of its proportions.
Trig. Help also offers a formula sheet, should you wish to calculate the values yourself.
A settings page allows you to easily specify your preferred number of decimal places, angle units (degrees/radians) & more.
Also available for iPhone & iPad.
