integral of (ye^{xy}-1/y)

Lösung

\int (y e^{x y} - \frac{1}{y}) d x

- \frac{x}{y} + e^{y x} + C

Schritte zur Lösung

\int y e^{x y} - \frac{1}{y} 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 \frac{1}{y} d x + \int y e^{y x} d x

\int \frac{1}{y} d x = \frac{x}{y}

\int y e^{y x} d x = e^{y x}

= - \frac{x}{y} + e^{y x}

Füge eine Konstante zur Lösung hinzu

= - \frac{x}{y} + e^{y x} + C

\int - 2 tan (2 x) sec (2 x) d x

\int \frac{1 - x}{2 - x} d x

\int \frac{5 t ^{4}}{t ^{5} + 2} d t

\int 25 + 16 x^{2} d x

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