integral of ln(x)*sin(x)

\int ln (x) \cdot sin (x) d x

- ln (x) cos (x) + Ci (x) + C

Solution steps

\int ln (x) sin (x) d x

Apply Integration By Parts

= - ln (x) cos (x) - \int - \frac{cos ( x )}{x} d x

\int - \frac{cos ( x )}{x} d x = - Ci (x)

= - ln (x) cos (x) - (- Ci (x))

Simplify

= - ln (x) cos (x) + Ci (x)

Add a constant to the solution

= - ln (x) cos (x) + Ci (x) + C

What is the integral of ln(x)*sin(x) ?
The integral of ln(x)*sin(x) is -ln(x)cos(x)+\Ci(x)+C
