Question

Verify the trig equation by substituting identities so that both sides match. Turn all forms of tan and cot o sin and sec.
cotxsec^(4)x = cotx+2tanx+tan^(3)x

Answer 1

Break it down to the basics — write all of those things in terms of sin x and cos x. After likely cancellation, you'll see some other some opportunities to do combination of fractions
