Answer 2

Step-by-step explanation:

Step1:- SecA=1/CosA

TanA=SinA/CosA

put SecA and TanA in left hand side equation and me get:-

=(1/CosA)(1-SinA)((1/CosA) +(SinA/CosA)

=(1/CosA)(1-SinA)((1+SinA)/CosA)

=(1/CosA)(((1)²-(SinA)²)/CosA)

=(1/CosA)((CosA)²/CosA)

=CosA²/CosA²=1

LHS=RHS

hence proved
