\frac{1}{sin (x)} + \frac{cos (x)}{sin (x)}

$\frac{1}{\sin (x)} + \frac{\cos (x)}{\sin (x)}$

단계 1

\frac{1}{sin (x)}

$\frac{1}{\sin (x)}$ 을

csc (x)

$\csc (x)$ 로 변환합니다.

csc (x) + \frac{cos (x)}{sin (x)}

$\csc (x) + \frac{\cos (x)}{\sin (x)}$

단계 2

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

$\frac{\cos (x)}{\sin (x)}$ 을

cot (x)

$\cot (x)$ 로 변환합니다.

csc (x) + cot (x)

$\csc (x) + \cot (x)$

⎡ ⎢ ⎣ \begin{matrix} x^{2} & \frac{1}{2} \sqrt{π} & \int x d x \end{matrix} ⎤ ⎥ ⎦

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