integral from 0 to T of (x^4-8x+7)

Lösung

\int_{0}^{T} (x^{4} - 8 x + 7) d x

\frac{T ^{5}}{5} - 4 T^{2} + 7 T

Schritte zur Lösung

\int_{0}^{T} x^{4} - 8 x + 7 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

= \int_{0}^{T} x^{4} d x - \int_{0}^{T} 8 x d x + \int_{0}^{T} 7 d x

\int_{0}^{T} x^{4} d x = \frac{T ^{5}}{5}

\int_{0}^{T} 8 x d x = 4 T^{2}

\int_{0}^{T} 7 d x = 7 T

= \frac{T ^{5}}{5} - 4 T^{2} + 7 T

\int_{0}^{1} \frac{1}{e ^{x} - e ^{- x}} d x

\int_{0}^{1} arctan (x^{2}) d x

\int_{0}^{1} 9 x^{4} + 16 x^{2} d x

\int_{0}^{1} π (x^{2} + 1)^{2} d x

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