integral of cot(32x)

\int cot (32 x) d x

\frac{1}{32} ln ∣ sin (32 x) ∣ + C

Solution steps

\int cot (32 x) d x

Rewrite using trig identities

= \int \frac{cos ( 32 x )}{sin ( 32 x )} d x

Apply u-substitution

: \int \frac{1}{32 u} d u

= \int \frac{1}{32 u} d u

Take the constant out:

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

= \frac{1}{32} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{32} ln ∣ u ∣

Substitute back

u = sin (32 x)

= \frac{1}{32} ln ∣ sin (32 x) ∣

Add a constant to the solution

= \frac{1}{32} ln ∣ sin (32 x) ∣ + C

\int x^{\frac{1}{2}} + 5 d x

\int \frac{2 z ^{2}}{y} d y

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

\int \frac{2 x ^{2} + 5 x + 16}{x ^{4} + 8 x ^{2} + 16} d x

\int \frac{ln ( 2 x )}{ln ( 4 x )} \frac{1}{x} d x
