integral of (sin(x))^3(cos(x))^2

Lösung

\int (sin (x))^{3} (cos (x))^{2} d x

- \frac{cos ^{3} ( x )}{3} + \frac{cos ^{5} ( x )}{5} + C

Schritte zur Lösung

\int (sin (x))^{3} (cos (x))^{2} d x

Vereinfache

= \int sin^{3} (x) cos^{2} (x) d x

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int (1 - cos^{2} (x)) sin (x) cos^{2} (x) d x

Wende U-Substitution an

= \int - u^{2} (1 - u^{2}) d u

Multipliziere aus

- u^{2} (1 - u^{2}) : - u^{2} + u^{4}

= \int - u^{2} + u^{4} d u

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int u^{2} d u + \int u^{4} d u

\int u^{2} d u = \frac{u ^{3}}{3}

\int u^{4} d u = \frac{u ^{5}}{5}

= - \frac{u ^{3}}{3} + \frac{u ^{5}}{5}

Setze in

u = cos (x)

ein

= - \frac{cos ^{3} ( x )}{3} + \frac{cos ^{5} ( x )}{5}

Füge eine Konstante zur Lösung hinzu

= - \frac{cos ^{3} ( x )}{3} + \frac{cos ^{5} ( x )}{5} + C

\frac{d}{d x} (ln (324 sin^{2} (x)))

\frac{d y}{d x} - 5 y = 8

\frac{\partial}{\partial x} (y e^{\frac{x}{z}})

\int \frac{4}{3 x + 2} d x

\frac{d}{d x} (4 4 x)
