Proving trig identities examples
WebbProve the identity: Example 1. Step 1) Split up the identity into the left side and right side. Since the right side has a denominator that is a binomial, let’s start with that side. We can easily multiply it by its conjugate 1 - cosx and the denominator should become 1 - cos^2x (difference of squares). Step 2) Continue to simplify the right ...
