- Step 1: Draw the terminal side of the angle.
- Step 2: Find reference angle. (It is the smallest angle that you can make from the terminal side of an angle with the \(x\)-axis.)
- Step 3: Find the trigonometric function of the reference angle.

Degrees \(=\) Radians \(\times \frac{180}{π}\)
Example:
Convert \(\frac{ 2π}{3}\) to degrees.
\(\frac{2\ π}{3} \times \frac{180}{π} \ = \ \frac{360π}{3π} \ = \ 120\)
