Schritte zur Lösung

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

\int_{1}^{2} \frac{1}{4 x ^{2}} d x = \frac{1}{8}

= \frac{7}{3} + \frac{1}{8}

Vereinfache

\frac{7}{3} + \frac{1}{8} : \frac{59}{24}

= \frac{59}{24}

\int \frac{y}{2 x + 3 y} d x

\frac{d}{d x} (x^{2} e^{x} cos (2 x))

\frac{d}{d x} (- 6 cot (x) csc (x))

\frac{\partial}{\partial x} ((1 + 2 x^{2}) (x - x^{2}))
