integral of 1/(sqrt(x))sin(sqrt(x))

\int \frac{1}{x} sin (x) d x

- 2 cos (x) + C

Solution steps

\int \frac{1}{x} sin (x) d x

Apply u-substitution

= \int 2 sin (u) d u

Take the constant out:

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

= 2 \cdot \int sin (u) d u

Use the common integral:

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

= 2 (- cos (u))

Substitute back

u = x

= 2 (- cos (x))

Simplify

= - 2 cos (x)

Add a constant to the solution

= - 2 cos (x) + C
