Question

${8 \cot}^{2} a \: - {8 \cosec}^{2}a = \\ (a) \: 8 \\ (b) \frac{1}{8} \\ (c) - 8 \\ (d) - \frac{1}{8}$
$pls \: answer \: the \: question \: with \: step - by - step \: explaination$
​

Answer 1

Answer:

c) -8

step by step explanation:

8Cot^2 a - 8Cosec^2 a

-8(Cosec^2 a - Cot^2 a)

-8(1) ......[ °.° cosec^o - cot^2o = 1]

= -8
