Question

prove that(1-sinA)(secA+tanA)=1

Answer 1

Hey mate ,

A little change in the question

QUESTION: Prove that

$(1 - \sin(x) )( \sec(x) + \tan(x) ) = \cos(x)$

Proof:. (See the picture carefully)

Identities used are:

$(x - y)(x + y) = {x}^{2} + {y}^{2} \\ and \\ {sin}^{2} x + { \cos }^{2}x = 1$
