Question

Simply using trigonometric identities
(cosec² A-cot² A) (sec² A - tan² A)

please help me I will mark u as brainliest and I will follow you ​

Answer 1

Answer:

1

Step-by-step explanation:

cosec^2 A - cot^2 A = 1 and sec^2 A - tan^2 A = 1

So, 1 x 1 = 1

Answer 2

Answer:

(cosec^2a-cot^2a)(sec^2a-tan^2a)

=( 1+cot^2a- cot^2a) (1+tan^2a-tan^2a)

=(1) (1)

=2
