1. ### Prove the following identities sec (x) - sin(x) = [tan^2(x) + cos^2(x)] / [ sec (x) + sin(x)]?

sec (x) - sin(x) = [tan^2(x) + cos^2(x)] / [ sec (x) + sin(x)] LS: sec (x) - sin(x) = [ sec (x) - sin...x) = 1 dividing through by cos^2(x) tan^2(x) + 1 = sec ^2(x) tan^2(x) = sec ^2(x) - 1 resubstituting tan^2(x): = sec ...
