integral from 2 to 5 of c(1+x)

Lösung

\int_{2}^{5} c (1 + x) d x

\frac{27}{2} c

Schritte zur Lösung

\int_{2}^{5} c (1 + x) d x

Entferne die Konstante:

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

= c \cdot \int_{2}^{5} 1 + x 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

= c (\int_{2}^{5} 1 d x + \int_{2}^{5} x d x)

\int_{2}^{5} 1 d x = 3

\int_{2}^{5} x d x = \frac{21}{2}

= c (3 + \frac{21}{2})

Füge

3 + \frac{21}{2}

zusammen:

\frac{27}{2}

= \frac{27}{2} c

\int_{- π}^{x^{2}} sin (t^{2}) d t

\int_{0}^{3} t e^{- 0.3 t} d t

\int_{3}^{6} x^{3} d x

\int_{1}^{2} (x^{2} - \frac{1}{x ^{2}}) d x

\int_{3}^{5} 7 d x
