Lösung

\int_{0}^{\frac{π}{4}} 7 sec^{2} (t) d t

7

Schritte zur Lösung

\int_{0}^{\frac{π}{4}} 7 sec^{2} (t) d t

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 7 \cdot \int_{0}^{\frac{π}{4}} sec^{2} (t) d t

Nutze das gemeinsame Integral :

\int sec^{2} (t) d t = tan (t)

= 7 [tan (t)]_{0}^{\frac{π}{4}}

Berechne die Grenzen:

1

= 7 \cdot 1
