integral from 0 to pi of xsin(x^2)

\int_{0}^{π} x sin (x^{2}) d x

\frac{1}{2} (- cos (π^{2}) + 1)

Decimal Notation

0.95134 \dots

Solution steps

\int_{0}^{π} x sin (x^{2}) d x

Apply u-substitution

: \int_{0}^{π^{2}} \frac{sin ( u )}{2} d u

= \int_{0}^{π^{2}} \frac{sin ( u )}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int_{0}^{π^{2}} sin (u) d u

Use the common integral:

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

= \frac{1}{2} [- cos (u)]_{0}^{π^{2}}

Compute the boundaries:

- cos (π^{2}) + 1

= \frac{1}{2} (- cos (π^{2}) + 1)

\int_{0}^{x} 10 e^{- 2 x - 3 y} d y

\int_{0}^{\frac{π}{2}} sin^{4} (t) d t

\int_{0}^{\frac{π}{2}} \frac{x}{1 + cos ( x )} d x

\int_{0}^{3} \frac{1}{1 + x + 1} d x

\int_{0}^{2} 9 y^{2} y^{3} + 1 d y
