integral from 3 to 9 of (1+x^2)

Lösung

\int_{3}^{9} (1 + x^{2}) d x

240

Schritte zur Lösung

\int_{3}^{9} 1 + x^{2} 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_{3}^{9} 1 d x + \int_{3}^{9} x^{2} d x

\int_{3}^{9} 1 d x = 6

\int_{3}^{9} x^{2} d x = 234

= 6 + 234

Vereinfache

= 240

\int \frac{24}{( x - 2 ) ( x ^{2} + 4 )} d x

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

d er i v a t i v e y = e^{5 x}

x \to 2 lim (x^{2} - 5 x + 6)
