Question

The value of(1-sec^2A) cot^2A is

Answer 1

Answer:

-1

Step-by-step explanation:

Given

$(1-sec^2A) cot^2A\\\\(sec^2A-1) -cot^2A\\(tan^2A)-cot^2A\\\\-1$

We need to take -1 common and then convert it into tan function we know tan and cot are reciprocal functions of each other hence cancel out for the same angle A.

Answer 2

Answer:

(1-sec²A)cot²A

(-tan²A)(cot²A)

-1
