Answer 2

Solution--->

1) plzzz refer the attachment

2) In second step we divide numerator and denominator by CosA and using

tanA = SinA /CosA , SecA = 1 / CosA

3) In fourth step we use

Sec²A - tan²A = 1

4) In 5th step we use a² - b² = ( a + b ) ( a - b )

5) In 7th step we take ( SecA - tanA ) as common from denominator and ( tanA + SecA - 1 ) cancel out from numerator and denominator and we get RHS
