Graph of f(x) = 2 * x^6 with the area from 0 to 1 shaded. The shaded area equals the definite integral, about 0.28571429.

How to work it out

  1. 1

    We want an antiderivative of f(x) = 2 * x6x^{6}.

    āˆ«2x6ā€‰dx\int 2 x^{6}\,dx
  2. 2

    Method: constant multiple and power rule.

  3. 3

    That gives the antiderivative; add the constant C because any constant disappears when you differentiate:

    āˆ«2x6ā€‰dx=2x77+C\int 2 x^{6}\,dx = \frac{2 x^{7}}{7} + C
  4. 4

    Check by differentiating the answer; you must get the original function back:

    ddx[2x77]=98x649\frac{d}{dx}\left[\frac{2 x^{7}}{7}\right] = \frac{98 x^{6}}{49}
  5. 5

    As a definite integral, evaluate the antiderivative at both ends and subtract. Between 0 and 1:

    āˆ«012x6ā€‰dx=[2x77]01ā‰ˆ0.28571429\int_{0}^{1} 2 x^{6}\,dx = \Big[\frac{2 x^{7}}{7}\Big]_{0}^{1} \approx 0.28571429
LaTeX source of the formulas on this page
\[ \int 2 x^{6}\,dx = \frac{2 x^{7}}{7} + C \]
\[ \int 2 x^{6}\,dx \]
\[ \frac{d}{dx}\left[\frac{2 x^{7}}{7}\right] = \frac{98 x^{6}}{49} \]
\[ \int_{0}^{1} 2 x^{6}\,dx = \Big[\frac{2 x^{7}}{7}\Big]_{0}^{1} \approx 0.28571429 \]
