integral from 0 to 4 of 5x^2+3x+1

\int_{0}^{4} 5 x^{2} + 3 x + 1 d x

\frac{404}{3}

Decimal Notation

134.66666 \dots

Solution steps

\int_{0}^{4} 5 x^{2} + 3 x + 1 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} 5 x^{2} d x + \int_{0}^{4} 3 x d x + \int_{0}^{4} 1 d x

\int_{0}^{4} 5 x^{2} d x = \frac{320}{3}

\int_{0}^{4} 3 x d x = 24

\int_{0}^{4} 1 d x = 4

= \frac{320}{3} + 24 + 4

Simplify

\frac{320}{3} + 24 + 4 : \frac{404}{3}

= \frac{404}{3}

\int_{0}^{8} (x^{2} - 5) d x

\int_{\frac{π}{2}}^{π} 0 d x

\int_{0}^{\frac{π}{3}} 2 x cos (x) d x

\int_{1}^{9} - x^{2} + 10 x - 9 d x

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