Answer 2

Explanation:

Question:-

(sec A+tan A) (1 - sin A)

Solution:-

$( \frac{1}{ \cot(a) } + \frac{ \sin(a) }{ \cos(a) } ) \: (1 - \sin(a ))$

$\frac{(1 + \sin(a)1 - \sin(a) }{ \cos(a) }$

$= \frac{1 - { \sin }^{2} a}{ \cos(a) }$

$= \frac{ { \cos }^{2} a}{ \cos(a) }$

$= \cos(a)$

(sec A+tan A) (1 - sin A) =CosA
