Help please! I need to prove this using identities
show all steps

cos(pi/2+x)/cos(pi+x)=tanx

 see proof below

Step-by-step explanation:

Use the Sum & Difference Identity: cos (A + B) = cos A · cos B - sin A · sin B

Recall the following from Unit Circle: cos (π/2) = 0, sin (π/2) = 1

                                                              cos (π) = -1,   sin (π) = 0    

Use the Quotient Identity:  

Proof LHS → RHS:

Quotient:                 tan x

LHS = RHS

can someone answer this question plz
