Solve ∫ (from 0 to 10) of x^2+5=

$$\int _ { 0 } ^ { 10 } x ^ { 2 } + 5 =$$

Evaluate

$$\frac{1150}{3}\approx 383.333333333$$

Solution Steps

Evaluate the indefinite integral first.

$$\int x^{2}+5\mathrm{d}x$$

Integrate the sum term by term.

$$\int x^{2}\mathrm{d}x+\int 5\mathrm{d}x$$

Since \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} for k\neq -1, replace \int x^{2}\mathrm{d}x with \frac{x^{3}}{3}.

$$\frac{x^{3}}{3}+\int 5\mathrm{d}x$$

Find the integral of 5 using the table of common integrals rule \int a\mathrm{d}x=ax.

$$\frac{x^{3}}{3}+5x$$

The definite integral is the antiderivative of the expression evaluated at the upper limit of integration minus the antiderivative evaluated at the lower limit of integration.

$$\frac{10^{3}}{3}+5\times 10-\left(\frac{0^{3}}{3}+5\times 0\right)$$

Simplify.

$$\frac{1150}{3}$$
