integral from 0 to sqrt(pi of)4xcos(x^2)

\int_{0}^{π} 4 x cos (x^{2}) d x

0

Solution steps

\int_{0}^{π} 4 x cos (x^{2}) d x

Take the constant out:

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

= 4 \cdot \int_{0}^{π} x cos (x^{2}) d x

Apply u-substitution

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

= 4 \cdot \int_{0}^{π} \frac{cos ( u )}{2} d u

Take the constant out:

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

= 4 \cdot \frac{1}{2} \cdot \int_{0}^{π} cos (u) d u

Use the common integral:

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

= 4 \cdot \frac{1}{2} [sin (u)]_{0}^{π}

Simplify

4 \cdot \frac{1}{2} [sin (u)]_{0}^{π} : 2 [sin (u)]_{0}^{π}

= 2 [sin (u)]_{0}^{π}

Compute the boundaries:

0

= 2 \cdot 0

Simplify

= 0

\frac{d x}{d t} = x - 1

\int \frac{1}{( 1 + x ) ^{4}} d x

x \to \frac{π}{2} lim (cot (x))

n = 5 \sum \infty \frac{1}{2 ^{n}}

\frac{d}{d x} (7 x^{2} ln (x))
