integral from 0 to 3 of (t^2i+tj-2k)

Lösung

\int_{0}^{3} (t^{2} i + t j - 2 k) d t

\frac{- 12 k + 9 j}{2} + 9 i

Schritte zur Lösung

\int_{0}^{3} t^{2} i + t j - 2 k 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}^{3} t^{2} i d t + \int_{0}^{3} t j d t - \int_{0}^{3} 2 k d t

\int_{0}^{3} t^{2} i d t = i 9

\int_{0}^{3} t j d t = \frac{9 j}{2}

\int_{0}^{3} 2 k d t = 6 k

= i 9 + \frac{9 j}{2} - 6 k

Schreibe

i 9 + \frac{9 j}{2} - 6 k

in der Standard komplexen Form um:

\frac{9 j - 12 k}{2} + 9 i

= \frac{- 12 k + 9 j}{2} + 9 i

\int_{0}^{π} sin^{2} (x) \cdot cos (x) d x
