Question

How do you simplify $\frac{1}{\sin x}$?

Answer 1

Simplify the given expression:

The given expression is

We know that $\sin x=\frac{oppositeside}{hypotenuse}$

$\therefore \frac{1}{\sin x}=\frac{hypotenuse}{oppositeside}$

$=\cos exx$

$\therefore \frac{1}{\sin x}=\cos ecx$

Hence, $\frac{1}{\sin x}$ can be simplified into $\cos ecx$.
