integral from-2 to x of (20t^2-19t)

Lösung

\int_{- 2}^{x} (20 t^{2} - 19 t) d t

\frac{20 ( x ^{3} + 8 )}{3} - 19 (\frac{x ^{2}}{2} - 2)

Schritte zur Lösung

\int_{- 2}^{x} 20 t^{2} - 19 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_{- 2}^{x} 20 t^{2} d t - \int_{- 2}^{x} 19 t d t

\int_{- 2}^{x} 20 t^{2} d t = \frac{20 ( x ^{3} + 8 )}{3}

\int_{- 2}^{x} 19 t d t = 19 (\frac{x ^{2}}{2} - 2)

= \frac{20 ( x ^{3} + 8 )}{3} - 19 (\frac{x ^{2}}{2} - 2)

\int_{\frac{π}{2}}^{\frac{3 π}{2}} 2 cos (x) d x

\int_{0}^{2} \frac{1}{1 + x ^{4}} d x

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

\int_{- 1}^{x} e^{y^{2}} d y

\int_{4}^{9} 2 x (10 x + 3) d x
