Answer 2

$8cot^2A-8cosec^2 A=-8$

Step-by-step explanation:

Given:$8cot^2A-8cosec^2 A$

Taking common 8

$8(cot^2 A-cosec^2 A)$

Taking(-1) common in given terms in the bracket

$-8(cosec^2 A-cot^2 A)$

We know that

$cosec^2 A-cot^2 A=1$

Using the formula then, we get

$-8(1)$

After multiplying we get

=-8

$8cot^2A-8cosec^2 A=-8$
