integral of (sin(x^2))x

\int (sin (x^{2})) x d x

- \frac{1}{2} cos (x^{2}) + C

Solution steps

\int sin (x^{2}) x d x

Apply u-substitution

: \int \frac{sin ( u )}{2} d u

= \int \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 sin (u) d u

Use the common integral:

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

= \frac{1}{2} (- cos (u))

Substitute back

u = x^{2}

= \frac{1}{2} (- cos (x^{2}))

Simplify

= - \frac{1}{2} cos (x^{2})

Add a constant to the solution

= - \frac{1}{2} cos (x^{2}) + C

\int x \cdot 2 x - 1 d x

\int 2 e^{x} + 7 d x

\int (2 x + 3 cos (x)) d x

\int \frac{sec ^{6} ( θ )}{tan ^{2} ( θ )} d θ

\int a \cdot e^{- a x} d x
