integral of (x-3)cos(x)

Lösung

\int (x - 3) cos (x) d x

sin (x) (x - 3) + cos (x) + C

Schritte zur Lösung

\int (x - 3) cos (x) d x

Wende die partielle Integration an

= sin (x) (x - 3) - \int sin (x) d x

\int sin (x) d x = - cos (x)

= sin (x) (x - 3) - (- cos (x))

Vereinfache

= sin (x) (x - 3) + cos (x)

Füge eine Konstante zur Lösung hinzu

= sin (x) (x - 3) + cos (x) + C

x \to 3 + lim (e^{\frac{x}{3 - x}})

\frac{\partial}{\partial θ} (- cos (θ))

a re a y = x, y = \frac{1}{3} x, x = 16

x \to 3 lim ((x^{2} + 4 x - 2)^{2})

\frac{d}{d a} ((x - a)^{2})
