t (1 + t) : t + t^{\frac{3}{2}}

= \int_{1}^{9} t + t^{\frac{3}{2}} d t

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}^{9} t d t + \int_{1}^{9} t^{\frac{3}{2}} d t

\int_{1}^{9} t d t = \frac{52}{3}

\int_{1}^{9} t^{\frac{3}{2}} d t = \frac{484}{5}

= \frac{52}{3} + \frac{484}{5}

Vereinfache

\frac{52}{3} + \frac{484}{5} : \frac{1712}{15}

= \frac{1712}{15}

\int_{- 2}^{0} x^{2} 1 - x^{3} d x

\int_{0}^{a r c t a n (x)} sec^{2} (t) d t

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

\int_{0}^{1} x^{3} - 3 x^{2} + 2 d x

\int_{0}^{\infty} e^{- y} (2 y^{3} - \frac{2 y ^{3}}{3}) d y
