$\frac{\cos (x)}{\sin (x)} - \frac{\sin (x)}{\cos (x)}$

चरण 1

$\frac{\cos (x)}{\sin (x)}$ को $\cot (x)$ में बदलें.

$\cot (x) - \frac{\sin (x)}{\cos (x)}$

चरण 2

$\frac{\sin (x)}{\cos (x)}$ को $\tan (x)$ में बदलें.

$\cot (x) - \tan (x)$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
