(4 + 2 y)^{2} : 16 + 16 y + 4 y^{2}

= \int_{2}^{3} 16 + 16 y + 4 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_{2}^{3} 16 d y + \int_{2}^{3} 16 y d y + \int_{2}^{3} 4 y^{2} d y

\int_{2}^{3} 16 d y = 16

\int_{2}^{3} 16 y d y = 40

\int_{2}^{3} 4 y^{2} d y = \frac{76}{3}

= 16 + 40 + \frac{76}{3}

Vereinfache

16 + 40 + \frac{76}{3} : \frac{244}{3}

= \frac{244}{3}

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

\int_{- 3}^{- 2} x^{2} + 5 x + 6 d x

\int_{0}^{\frac{π}{3}} (4 sec^{2} (x)) d x

\int_{1}^{9} \frac{9}{x} - \frac{x}{9} d x

\int_{0}^{l} x l sin (\frac{nπ x}{l}) d x
