Verifying Trigonometric Identities

This section features many problems in which a combination of trig functions must be changed to look like another set of trig functions. These problems are not that difficult now, as we have memorized many trig identities. Strategies on these problems:

• Work with only one side of the equation (choose the more complicated side). 
• Try to convert everything to sines and cosines.
• Simplify complex parts of the problem ASAP using trig identities.
