$$$\sec^{2}{\left(x \right)}$$$ 的積分

此計算器將求出 $$$\sec^{2}{\left(x \right)}$$$ 的不定積分（原函數），並顯示步驟。

求$$$\int \sec^{2}{\left(x \right)}\, dx$$$。

$$$\sec^{2}{\left(x \right)}$$$ 的積分是 $$$\int{\sec^{2}{\left(x \right)} d x} = \tan{\left(x \right)}$$$：

$${\color{red}{\int{\sec^{2}{\left(x \right)} d x}}} = {\color{red}{\tan{\left(x \right)}}}$$

因此，

$$\int{\sec^{2}{\left(x \right)} d x} = \tan{\left(x \right)}$$

加上積分常數：

$$\int{\sec^{2}{\left(x \right)} d x} = \tan{\left(x \right)}+C$$

$$$\int \sec^{2}{\left(x \right)}\, dx = \tan{\left(x \right)} + C$$$A
