integral of (3tan(w)-4cos^2(w))/(cos(w))

Lösung

\int \frac{3 tan ( w ) - 4 cos ^{2} ( w )}{cos ( w )} d w

Lösung

3 sec (w) - 4 sin (w) + C

Schritte zur Lösung

\frac{3 tan ( w ) - 4 cos ^{2} ( w )}{cos ( w )} : \frac{3 tan ( w )}{cos ( w )} - 4 cos (w)

= \int \frac{3 tan ( w )}{cos ( w )} - 4 cos (w) d w

Wende die Summenregel an:

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

= \int \frac{3 tan ( w )}{cos ( w )} d w - \int 4 cos (w) d w

\int \frac{3 tan ( w )}{cos ( w )} d w = 3 sec (w)

\int 4 cos (w) d w = 4 sin (w)

= 3 sec (w) - 4 sin (w)

Füge eine Konstante zur Lösung hinzu

= 3 sec (w) - 4 sin (w) + C
