integral from 0 to 1 of x^6sin(x^7)

\int_{0}^{1} x^{6} sin (x^{7}) d x

\frac{1}{7} (- cos (1) + 1)

Decimal

0.06567 \dots

Solution steps

\int_{0}^{1} x^{6} sin (x^{7}) d x

Apply u-substitution

= \int_{0}^{1} \frac{sin ( u )}{7} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{7} \cdot \int_{0}^{1} sin (u) d u

Use the common integral:

\int sin (u) d u = - cos (u)

= \frac{1}{7} [- cos (u)]_{0}^{1}

Compute the boundaries:

- cos (1) + 1

= \frac{1}{7} (- cos (1) + 1)
