解析 対数の積分(部分分数分解)

(練習用問題)

積分しなさい
\begin{align} \int_{x=1}^{x=2} {1 \over x^2+2x} \, dx \end{align}
\begin{align} \int {1 \over (x-1)(x-4)} \, dx \end{align}
\begin{align} \int_{x=0}^{x=1}{1\over ( \qquad )} \left\{ {1 \over (x+2)} - {1\over (x+5)} \right\}\, dx \end{align}
部分分数分解しなさい \begin{align} {1 \over s^2 (s^2-4) } \end{align}
\begin{align} {1 \over s (s^2+4) } \end{align}
積分しなさい
\begin{align} \int {1 \over x (x+2)(x+5)} \, dx \end{align}
\begin{align} \int {1 \over x^2-9} \, dx \end{align}
\begin{align} \int {x^2+2x+1 \over x^2+1} \, dx \end{align}
\begin{align} \int {1 \over x^2-5x+4} \, dx \end{align}
\begin{align} \int {2x-5 \over x^2-5x+4} \, dx \end{align}
