integral of-xy^2+cos(x)sin(x)

Lösung

\int - x y^{2} + cos (x) sin (x) d x

\frac{sin ^{2} ( x )}{2} - \frac{y ^{2} x ^{2}}{2} + C

Schritte zur Lösung

\int - x y^{2} + cos (x) sin (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 cos (x) sin (x) d x - \int y^{2} x d x

\int cos (x) sin (x) d x = \frac{sin ^{2} ( x )}{2}

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

= \frac{sin ^{2} ( x )}{2} - \frac{y ^{2} x ^{2}}{2}

Füge eine Konstante zur Lösung hinzu

= \frac{sin ^{2} ( x )}{2} - \frac{y ^{2} x ^{2}}{2} + C

\int (\frac{3}{x} + sec^{2} (x)) d x

\int (3 x + 1)^{\frac{3}{2}} d x

\int \frac{4 x + 5}{x ^{2} + x - 2} d x

\int y^{6} (y^{2} + 4 y - 5) d y

\int ln (y^{3}) d y
