t (t - sin (t)) : t^{2} - t sin (t)

= \int_{0}^{x} t^{2} - t sin (t) 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_{0}^{x} t^{2} d t - \int_{0}^{x} t sin (t) d t

\int_{0}^{x} t^{2} d t = \frac{x ^{3}}{3}

\int_{0}^{x} t sin (t) d t = sin (x) - x cos (x)

= \frac{x ^{3}}{3} - (sin (x) - x cos (x))

Vereinfache

= \frac{x ^{3}}{3} - sin (x) + x cos (x)

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

\int_{0}^{4} \frac{1}{6 x + 1} d x

\int_{3}^{- 3} (6 x + 5)^{2} d x

\int_{0}^{1} 5^{2 t - 2} d t

\int_{0}^{b} e^{- s t} d t
