Question

Verify that the equation is an identity. 1 / (1 - cos x) + 1 / (1 + cos x) = 2 / sin^2 x To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step. 1 / (1 - cos x) + 1 / (1 + cos x) = [ ] + [ ] Express each fraction over the lowest common denominator. = [ ] Add the fractions together. = 2 / sin^2 x [ ]
