$$$\sec^{2}{\left(x \right)}$$$の積分

この計算機は、手順を示しながら$$$\sec^{2}{\left(x \right)}$$$の不定積分（原始関数）を求めます。

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

$$$\sec^{2}{\left(x \right)}$$$ の不定積分は $$$\int{\sec^{2}{\left(x \right)} d x} = \tan{\left(x \right)}$$$ です:

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

したがって、

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

積分定数を加える:

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

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