\int_{0}^{1} π (7 x^{2})^{2} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= π \cdot \int_{0}^{1} (7 x^{2})^{2} d x

Vereinfache

(7 x^{2})^{2} : 49 x^{4}

= π \cdot \int_{0}^{1} 49 x^{4} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= π 49 \cdot \int_{0}^{1} x^{4} d x

Wende die Potenzregel an

= π 49 [\frac{x ^{5}}{5}]_{0}^{1}

Berechne die Grenzen:

\frac{1}{5}

= π 49 \cdot \frac{1}{5}

Vereinfache

= \frac{49 π}{5}

\int_{1}^{2} x^{\frac{3}{5}} d x

\int_{0.2}^{1.2} e^{x^{2}} d x

\int_{- 2}^{2} (4 + y^{2}) - (2 y^{2}) d y

\int_{7}^{9} x^{3} - 10 x^{2} + 21 x d x

\int_{0}^{1} (y - y^{2}) d y
