integral of 8sin(ln(x))

\int 8 sin (ln (x)) d x

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

Solution steps

\int 8 sin (ln (x)) d x

Take the constant out:

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

= 8 \cdot \int sin (ln (x)) d x

Apply Integration By Parts

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

= 8 (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))

= 8 (x sin (ln (x)) - (\frac{1}{2} x sin (ln (x)) + \frac{1}{2} x cos (ln (x))))

Expand

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))

= 8 (\frac{1}{2} x sin (ln (x)) - \frac{1}{2} x cos (ln (x)))

Add a constant to the solution

= 8 (\frac{1}{2} x sin (ln (x)) - \frac{1}{2} x cos (ln (x))) + C

2 x^{2} + x y - y^{2}

2 1 - y

\int x 3 81 + x^{2} d x

\frac{\partial}{\partial x} (7 - 2 x^{2} - y^{2})

\int 20 e^{u} d u
