Question

(secA+ tan A) (1-sin A ) = cosA​

Answer 1

Answer:

Step-by-step explanation:

Hello

===================================

Given us,

( secA + tanA ) ( 1 - sinA )

we know that

secA = 1/cosA

tanA = sins/cosA

now

( 1 /cosA + sinA /cosA ) ( 1 - sinA )

= ( 1 + sinA ) ( 1 - sinA )/ cosA

= 1² - sin²A / cosA

= cos²A / cosA

= cosA

RHS
