Question

find the valur of:
20 cosec² A - 20 cot² A​

Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Find the value of $20 \cosec^{2} \alpha - 20 \cot^{2} \alpha$

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

$20 (\cosec^{2} \alpha - \cot^{2} \alpha )$

Now, we know that,

$(\cosec^{2} \alpha - \cot^{2} \alpha ) = 1$

So,

$20 (\cosec^{2} \alpha - \cot^{2} \alpha )$

$= 20 \times 1$

$= 20$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $20 \cosec^{2} \alpha - 20 \cot^{2} \alpha = 1$
