integral of 5sin(ln(x))

\int 5 sin (ln (x)) d x

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

Solution steps

\int 5 sin (ln (x)) d x

Take the constant out:

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

= 5 \cdot \int sin (ln (x)) d x

Apply Integration By Parts

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

= 5 (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))

= 5 (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))

= 5 (\frac{1}{2} x sin (ln (x)) - \frac{1}{2} x cos (ln (x)))

Add a constant to the solution

= 5 (\frac{1}{2} x sin (ln (x)) - \frac{1}{2} x cos (ln (x))) + C

f (x) = \frac{x}{x ^{2} + 36}

\int x^{2} (5 - x)^{4} d x

2 ln (x + 1)

n = 1 \sum \infty \frac{n !}{10 7 ^{n}}

\frac{d}{d x} (x^{3} + x y^{2} e^{\frac{x}{y}})
