# Summary of trigonometric identities You have seen quite a few trigonometric identities in the past few pages. It is convenient to have a summary of them for reference. These identities mostly refer to one angle denoted θ, but there are some that involve two angles, and for those, the two angles are denoted α and β.

### When working with trigonometric identities, it may be useful to keep the following tips in mind: Draw a picture illustrating the problem if it involves only the basic trigonometric functions. If the problem expresses an identity between trigonometric functions, try working on one side of the identity to write the trigonometric functions from one side in terms of trigonometric functions on the
