integral of ((cos(ln(x))))/x

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

sin (ln (x)) + C

Solution steps

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

Apply u-substitution

: \int cos (u) d u

= \int cos (u) d u

Use the common integral:

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

= sin (u)

Substitute back

u = ln (x)

= sin (ln (x))

Add a constant to the solution

= sin (ln (x)) + C

\int tan (3 x + 1) d x

\int (5 x^{5} + 20 e^{4 x} + x + 10) d x

\frac{4}{x}

\int \frac{5 x - 14}{x ^{3} - x ^{2} - 4 x + 4} d x

\int \frac{( 1 - x - y ) ^{2}}{2} d y
