$$$\ln\left(\tan{\left(x \right)} \sec{\left(x \right)}\right) \sec{\left(x \right)}$$$の積分

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

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