Include a minimum of 5 steps

Must include at least 3 uses of trig identities (stick to the Grade 11 ones). You may use the same identity more than once as long as there are 3 different ones used at some point.

Use a variety of algebraic skills (factoring, expanding, fractions, etc.)

Include an answer key to your problem

Include a brief paragraph explaining how you came up with your identity. This is an informal paragraph and I just want to see your thought process (i.e. what algebraic skills/trig identities did you want to include? Did you run into any difficulties? Are you particularly proud of anything you came up with? etc.)
