Schritte zur Lösung

\int_{0}^{\frac{π}{2}} 7 sin (t) - 2 cos (t) d t

Wende die Summenregel an:

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

= \int_{0}^{\frac{π}{2}} 7 sin (t) d t - \int_{0}^{\frac{π}{2}} 2 cos (t) d t

\int_{0}^{\frac{π}{2}} 7 sin (t) d t = 7

\int_{0}^{\frac{π}{2}} 2 cos (t) d t = 2

= 7 - 2
