integral of cos(x)+1/3 sin(x)-1/(x^2)

Lösung

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

sin (x) - \frac{1}{3} cos (x) + \frac{1}{x} + C

Schritte zur Lösung

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

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

\int \frac{1}{3} sin (x) d x = - \frac{1}{3} cos (x)

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

= sin (x) - \frac{1}{3} cos (x) - (- \frac{1}{x})

Vereinfache

= sin (x) - \frac{1}{3} cos (x) + \frac{1}{x}
