prove that
sinAcosA+1/sinA+cosA1=1/secAtanA

It is not clear whether the denominator is sin A or (sin A + cos A) or (sin A + cos A 1) on the left side. It is also not clear whether the denominator is sec A or (sec A  tan A) on the right side. Please use parentheses to clarify the meaning of typed equations. Otherwise we can't help you.
