integral of [sin(ln(x))]

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

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

Solution steps

\int sin (ln (x)) d x

Apply Integration By Parts

: x sin (ln (x)) - \int cos (ln (x)) d x

= x sin (ln (x)) - \int cos (ln (x)) d x

\int cos (ln (x)) d x = \frac{1}{2} x sin (ln (x)) + \frac{1}{2} x cos (ln (x))

= x sin (ln (x)) - (\frac{1}{2} x sin (ln (x)) + \frac{1}{2} x cos (ln (x)))

Simplify

x sin (ln (x)) - (\frac{1}{2} x sin (ln (x)) + \frac{1}{2} x cos (ln (x))) : \frac{1}{2} x sin (ln (x)) - \frac{1}{2} x cos (ln (x))

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

Add a constant to the solution

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

\frac{1}{2} x^{2}

\frac{\partial}{\partial x} (x^{3} + y^{3} - 27 x - 12 y)

\int 3 x^{3} e^{x} d x

\int t^{3} ln (t^{2}) d t

(- 2 cos (2 x) - sin (3 x) - 3)^{2}
