integral from 0 to x of (3t^2-t-4)

Lösung

\int_{0}^{x} (3 t^{2} - t - 4) d t

x^{3} - \frac{x ^{2}}{2} - 4 x

Schritte zur Lösung

\int_{0}^{x} 3 t^{2} - t - 4 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} 3 t^{2} d t - \int_{0}^{x} t d t - \int_{0}^{x} 4 d t

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

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

\int_{0}^{x} 4 d t = 4 x

= x^{3} - \frac{x ^{2}}{2} - 4 x

\int_{- \infty}^{- 2} \frac{2}{x + 1} d x

\int_{0}^{s i n (t)} \frac{1}{9 - u ^{2}} d u

\int_{0}^{x} y d y

\int_{1}^{4} \frac{x - 3}{x} d x

\int_{1}^{3} 7 e^{x + 2} d x
