integral from 0 to 4 of x^3+x-x^2

\int_{0}^{4} x^{3} + x - x^{2} d x

\frac{152}{3}

Decimal Notation

50.66666 \dots

Solution steps

\int_{0}^{4} x^{3} + x - x^{2} 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}^{4} x^{3} d x + \int_{0}^{4} x d x - \int_{0}^{4} x^{2} d x

\int_{0}^{4} x^{3} d x = 64

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

\int_{0}^{4} x^{2} d x = \frac{64}{3}

= 64 + 8 - \frac{64}{3}

Simplify

64 + 8 - \frac{64}{3} : \frac{152}{3}

= \frac{152}{3}

\int_{\frac{π}{4}}^{\frac{π}{2}} 4 cos^{4} (x) d x

\int_{- 2}^{3} x + 6 - x d x

\int_{1}^{2} 7 x^{2} - 57 x + 8 d x

\int_{1}^{2} - 2 e^{4 t - 6} d t

\int_{0}^{\frac{π}{24}} tan (12 θ) d θ
