integral from-1 to 1 of x^3+2x

\int_{- 1}^{1} x^{3} + 2 x d x

0

Solution steps

\int_{- 1}^{1} x^{3} + 2 x d x

If f(x) is an odd function and continuous at:

[- a, a]

then

\int_{- a}^{a} f (x) d x = 0

Parity of

x^{3} + 2 x :

Odd

= 0

\int_{0}^{π} e^{i t} d t

\int_{0}^{4} (x + 2) d x

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

\int_{e^{y}}^{y} (\frac{y ln ( x )}{x}) d x

\int_{0}^{0.1} 150 x d x
