integral of csc(5x)

\int csc (5 x) d x

\frac{1}{5} ln tan (\frac{5 x}{2}) + C

Solution steps

\int csc (5 x) d x

Apply u-substitution

: \int csc (u) \frac{1}{5} d u

= \int csc (u) \frac{1}{5} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int csc (u) d u

Apply u-substitution

: \int \frac{1}{v} d v

= \frac{1}{5} \cdot \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= \frac{1}{5} ln ∣ v ∣

Substitute back

= \frac{1}{5} ln tan (\frac{5 x}{2})

Add a constant to the solution

= \frac{1}{5} ln tan (\frac{5 x}{2}) + C

\frac{d}{d x} (a cos (4 x))

\int 9 cos^{2} (x) sin (2 x) d x

\frac{d y}{d x} + 0.4 x y = 9 x

\frac{d}{d t} (cot (t))

y = 3 x^{3} - 6 x
