\int_{1}^{\frac{3}{2}} 3 y - 2 y^{2} d y

Wende die Summenregel an:

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

= \int_{1}^{\frac{3}{2}} 3 y d y - \int_{1}^{\frac{3}{2}} 2 y^{2} d y

\int_{1}^{\frac{3}{2}} 3 y d y = \frac{15}{8}

\int_{1}^{\frac{3}{2}} 2 y^{2} d y = \frac{19}{12}

= \frac{15}{8} - \frac{19}{12}

Vereinfache

\frac{15}{8} - \frac{19}{12} : \frac{7}{24}

= \frac{7}{24}

\int_{5}^{8} \frac{30}{x} d x

\int_{0}^{π} - 0.1 cos (x) sin (x) d x

\int_{- 2}^{4} x^{2} - 2 x d x

\int_{0}^{100} 2 ((x^{2}) - a x) d x

\int_{0}^{1} 2 x \cdot e^{x} d x
