integral of [sqrt(x)(x^2-1)+csc^2(x)]

Lösung

\int [x (x^{2} - 1) + csc^{2} (x)] d x

\frac{2}{7} x^{\frac{7}{2}} - \frac{2}{3} x^{\frac{3}{2}} - cot (x) + C

Schritte zur Lösung

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

\int x (x^{2} - 1) d x = \frac{2}{7} x^{\frac{7}{2}} - \frac{2}{3} x^{\frac{3}{2}}

\int csc^{2} (x) d x = - cot (x)

= \frac{2}{7} x^{\frac{7}{2}} - \frac{2}{3} x^{\frac{3}{2}} - cot (x)
