integral from-1 to 5 of (3x^2+4x)

Lösung

\int_{- 1}^{5} (3 x^{2} + 4 x) d x

174

Schritte zur Lösung

\int_{- 1}^{5} 3 x^{2} + 4 x d x

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}^{5} 3 x^{2} d x + \int_{- 1}^{5} 4 x d x

\int_{- 1}^{5} 3 x^{2} d x = 126

\int_{- 1}^{5} 4 x d x = 48

= 126 + 48

Vereinfache

= 174

\int_{2}^{3} \frac{1}{ln ( x )} d x

\int_{0}^{2 π} 3 sin (t) cos (t) d t

\int_{a}^{b} x^{- 2} d x

\int_{- 7}^{7} \frac{1}{x ^{2}} d x

\int_{0}^{1} (2 t + 1) (e^{- s t}) d t
