integral from 0 to 4 of (x+1)-x/2

解

\int_{0}^{4} (x + 1) - \frac{x}{2} d x

解

8

解答ステップ

\int_{0}^{4} x + 1 - \frac{x}{2} d x

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}^{4} x d x + \int_{0}^{4} 1 d x - \int_{0}^{4} \frac{x}{2} d x

\int_{0}^{4} x d x = 8

\int_{0}^{4} 1 d x = 4

\int_{0}^{4} \frac{x}{2} d x = 4

= 8 + 4 - 4

簡素化

= 8
