integral from 0 to 1 of xcos(x^2)

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

\frac{1}{2} sin (1)

Decimal

0.42073 \dots

Solution steps

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

Apply u-substitution

: \int_{0}^{1} \frac{cos ( u )}{2} d u

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

Use the common integral:

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

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

Compute the boundaries:

sin (1)

= \frac{1}{2} sin (1)

\int_{0}^{\infty} y^{3} e^{- y} d y

\int_{0}^{1} 6 (1 - y) d y

\int_{1}^{2} 90 - \frac{110}{x + 3} d x

\int_{0}^{2 π} - 25 d t

\int_{2}^{7} ∣ x - 4 ∣ d x
