What is the integral from 0 to 20 of x^2-17x+70 ?

The integral from 0 to 20 of x^2-17x+70 is 2000/3

integral from 0 to 20 of x^2-17x+70

\int_{0}^{20} x^{2} - 17 x + 70 d x

\frac{2000}{3}

Decimal

666.66666 \dots

Solution steps

\int_{0}^{20} x^{2} - 17 x + 70 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}^{20} x^{2} d x - \int_{0}^{20} 17 x d x + \int_{0}^{20} 70 d x

\int_{0}^{20} x^{2} d x = \frac{8000}{3}

\int_{0}^{20} 17 x d x = 3400

\int_{0}^{20} 70 d x = 1400

= \frac{8000}{3} - 3400 + 1400

Simplify

\frac{8000}{3} - 3400 + 1400 : \frac{2000}{3}

= \frac{2000}{3}

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

\int_{0}^{1} - x^{2} - x + 2 d x

\int_{1}^{2} (12 x^{3} + \frac{6}{x ^{2}}) d x

\int_{\frac{π}{4}}^{\frac{π}{3}} - sec^{2} (θ) d θ

\int_{1}^{2} \frac{1}{3} d x
