Question

17. If cosec = √5 , find the value of :
(i) 2 - sin²- cos² ​

Answer 1

Answer:

$\textbf{The value of 2-sin^2\theta - cos^2\theta is 1}$

Step-by-step explanation:

$\textbf{Given:}$

$cosec\,\theta=\sqrt{5}$

$\text{Now}$

$2-sin^2\theta-cos^2\theta$

$=2-(sin^2\theta+cos^2\theta)$

$\text{Using}$

$\boxed{sin^2A+cos^2A=1}$
