integral from 0 to 2 of x(x^2-1)^3

\int_{0}^{2} x (x^{2} - 1)^{3} d x

10

Solution steps

\int_{0}^{2} x (x^{2} - 1)^{3} d x

Expand

x (x^{2} - 1)^{3} : x^{7} - 3 x^{5} + 3 x^{3} - x

= \int_{0}^{2} x^{7} - 3 x^{5} + 3 x^{3} - x d x

Apply the Sum Rule:

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

= \int_{0}^{2} x^{7} d x - \int_{0}^{2} 3 x^{5} d x + \int_{0}^{2} 3 x^{3} d x - \int_{0}^{2} x d x

\int_{0}^{2} x^{7} d x = 32

\int_{0}^{2} 3 x^{5} d x = 32

\int_{0}^{2} 3 x^{3} d x = 12

\int_{0}^{2} x d x = 2

= 32 - 32 + 12 - 2

Simplify

= 10

\frac{\partial}{\partial x} (x^{2} y + 4 x^{4} y)

n = 3 \sum \infty \frac{1}{n ( n + 1 )}

\int \frac{a e ^{θ} + b}{a e ^{θ} - b} d θ

y = \frac{1}{1 + e ^{- x}}

\frac{\partial}{\partial x} (e^{2 x} sin (2 y))
