writing x instead of theta in solution
(1+tan²x)cosxsinx
=(sec²x)cosxsinx
=(1/cos²x)cosxsinx
=(1/cosx)sinx
=sinx/cosx= tanx
write it on a paper so that u can understand better .

Step-by-step explanation:
LHS=
=(sec²theta).(cos theta.sin theta)
=(1/cos²theta)(cos theta.sin theta)
=sin theta/cos theta = Tan theta
Hence proved
