integral from 0 to 1.2 of (1-y/2)

解

\int_{0}^{1.2} (1 - \frac{y}{2}) d y

0.84

解答ステップ

\int_{0}^{1.2} 1 - \frac{y}{2} d y

総和規則を適用する:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1.2} 1 d y - \int_{0}^{1.2} \frac{y}{2} d y

\int_{0}^{1.2} 1 d y = 1.2

\int_{0}^{1.2} \frac{y}{2} d y = 0.36

= 1.2 - 0.36

= 0.84
