1. Using these identities, prove the following: 1. Choose an angle between 61° and 89°. 2. Prove the half-angle identities work using your chosen angle and half of that angle. (For example if I choose …

The double-angle identities are derived from the sum identities by adding an angle to itself.Determine whether the statement makes sense or does not make sense, and explain your reasoning.

In this module you have worked with many different trigonometric identities. These identities can be helpful for making precise calculations. For example, you can use identities to find the lengths of the …
