Question

Please help me!simplify​

Answer 1

Step-by-step explanation:

Recall that

$\sin (\frac{\pi}{2} - x) = \cos x$

$\cos (\frac{\pi}{2} - x) = \sin x$

So we can rewrite the given expression as

$\dfrac{\cos^2 x}{\sin^2 x} + (\sin^2 x + \cos^2 x)$

$\Rightarrow \dfrac{\cos^2 x}{\sin^2 x} + 1$

or

$\dfrac{\cos^2 x + \sin^2 x}{\sin^2 x} = \dfrac{1}{\sin^2 x} = \csc^2 x$

Answer 2
