integral from 0 to pi/3 of 2cos(x)+3

解

\int_{0}^{\frac{π}{3}} 2 cos (x) + 3 d x

解

3 + π

+1

十進法表記

4.87364 \dots

解答ステップ

\int_{0}^{\frac{π}{3}} 2 cos (x) + 3 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}^{\frac{π}{3}} 2 cos (x) d x + \int_{0}^{\frac{π}{3}} 3 d x

\int_{0}^{\frac{π}{3}} 2 cos (x) d x = 3

\int_{0}^{\frac{π}{3}} 3 d x = π

= 3 + π
