Question

(√secA +1)(√secA - 1)

Answer 1

Answer:

tan^2 A

Step-by-step explanation:

multiply,

(a+b)(a-b)=a^2 - b^2

= root sec^2-1^2

= sec^2 A-1

= tan^2 A

Answer 2

Answer:

The answer is secA - 1

Step-by-step explanation:

Given ::- (√secA + 1)(√secA - 1)

Solution::

(√secA)² - (1)²         ∵ (a+b)(a-b) = a² - b²

= secA -1

=

Therefore the answer is secA - 1
