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.

Cofunction Identities (in Degrees) The co-function or periodic identities can also be represented in degrees as: sin (90°−x) = cos x. cos (90°−x) = sin x. tan (90°−x) = cot x. cot (90°−x) = tan x. sec (90°−x) = cosec x. cosec (90°−x) = sec x.
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.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
