integral from x to 2x of (x^2+y^2)

Lösung

\int_{x}^{2 x} (x^{2} + y^{2}) d y

x^{3} + \frac{7 x ^{3}}{3}

Schritte zur Lösung

\int_{x}^{2 x} x^{2} + y^{2} d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{x}^{2 x} x^{2} d y + \int_{x}^{2 x} y^{2} d y

\int_{x}^{2 x} x^{2} d y = x^{3}

\int_{x}^{2 x} y^{2} d y = \frac{7 x ^{3}}{3}

= x^{3} + \frac{7 x ^{3}}{3}

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

\int_{- 3}^{0} (x + 3) d x

\int_{- 7}^{2} (- x^{2} - 3 x) d x

\int_{- 3}^{0} x + 4 d x

\int_{4}^{1} x^{2} d x
