Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. A basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a. The formula to convert radians to degrees: degrees = radians * 180 / π.

Detailed step by step solutions to your Trigonometric Identities problems with our math solver and online calculator.
The Trigonometric Identities are equations that are true for Right Angled Triangles. (If it isn't a Right Angled Triangle use the Triangle Identities page) Each side of a right triangle has a name: Adjacent is always next to the angle. And Opposite is opposite the angle.
There are many different ways to prove an identity. Here are some guidelines in case you get stuck: 1) Work on the side that is more complicated. Try and simplify it. 2) Replace all trigonometric functions with just \sin \theta sinθ and \cos \theta cosθ where possible.
