Graph of f(x) = x^11 with the area from 0 to 1 shaded. The shaded area equals the definite integral, about 0.083333333.

How to work it out

1
We want an antiderivative of f(x) = $x^{11}$ .
$\int x^{11}\,dx$
2
Method: power rule: ∫xⁿ dx = xⁿ⁺¹/(n+1).
3
That gives the antiderivative; add the constant C because any constant disappears when you differentiate:
$\int x^{11}\,dx = \frac{x^{12}}{12} + C$
4
Check by differentiating the answer; you must get the original function back:
$\frac{d}{dx}\left[\frac{x^{12}}{12}\right] = \frac{144 x^{11}}{144}$
5
As a definite integral, evaluate the antiderivative at both ends and subtract. Between 0 and 1:
$\int_{0}^{1} x^{11}\,dx = \Big[\frac{x^{12}}{12}\Big]_{0}^{1} \approx 0.083333333$

\[ \int x^{11}\,dx = \frac{x^{12}}{12} + C \]
\[ \int x^{11}\,dx \]
\[ \frac{d}{dx}\left[\frac{x^{12}}{12}\right] = \frac{144 x^{11}}{144} \]
\[ \int_{0}^{1} x^{11}\,dx = \Big[\frac{x^{12}}{12}\Big]_{0}^{1} \approx 0.083333333 \]
