integral from 0 to 1 of sin(pi*x)

\int_{0}^{1} sin (π \cdot x) d x

\frac{2}{π}

Decimal Notation

0.63661 \dots

Solution steps

\int_{0}^{1} sin (π x) d x

Apply u-substitution

: \int_{0}^{π} sin (u) \frac{1}{π} d u

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

Take the constant out:

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

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

Use the common integral:

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

= \frac{1}{π} [- cos (u)]_{0}^{π}

Compute the boundaries:

2

= \frac{1}{π} \cdot 2

Simplify

= \frac{2}{π}

x \to 3 lim (\frac{x ^{2} - 2}{x - 3})

5 x (x + 6 y) y^{^{'}} = 5 y (x - 6 y)

10 e^{2 t}

- 18 x^{2} + 9 x + 30

x \to 0 - lim (x^{\frac{2}{3}})
