(x + \frac{1}{x})^{2} : x + 2 + \frac{1}{x}

= \int x + 2 + \frac{1}{x} 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 x d x + \int 2 d x + \int \frac{1}{x} d x

\int x d x = \frac{x ^{2}}{2}

\int 2 d x = 2 x

\int \frac{1}{x} d x = ln ∣ x ∣

= \frac{x ^{2}}{2} + 2 x + ln ∣ x ∣

\frac{\partial}{\partial z} (e^{z^{2}})

\int 7 \frac{cos ( x ) + sin ( x )}{sin ( 2 x )} d x

\frac{\partial}{\partial x} (x^{y^{2}})

\frac{\partial}{\partial y} (3 x^{2} y^{2} - 2)
