面积 4-x^2,x-2

解答

面积

4 - x^{2}, x - 2

\frac{125}{6}

十进制

20.83333 \dots

求解步骤

使用面积公式:

\int_{- 3}^{2} 4 - x^{2} - (x - 2) d x

解

\int_{- 3}^{2} 4 - x^{2} - (x - 2) d x : \frac{125}{6}

面积为:

= \frac{125}{6}

\int \frac{1}{9 + 2 x} d x

\int \frac{x ^{2}}{3 x} d x

\frac{d}{d x} (ln^{2} (2) \cdot 2^{x} - \frac{1}{x ^{2}})

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

\frac{d}{d y} (4 y^{3} - 5 y^{3} cos (y) + 2 y^{5} sin (y))
