integral of sin(ln(u))

\int sin (ln (u)) d u

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

Solution steps

\int sin (ln (u)) d u

Apply Integration By Parts

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

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

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

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

Simplify

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

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

Add a constant to the solution

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

y^{^{''}} - y = 5 sin (2 t) (0) 1

\frac{1}{2 + 3 x}

y^{^{'}} = y + x, y (0) = - 1

\frac{r}{r ^{2} + 1}

\int (- 0.5 x + 450) d x
