integral of csc^2(2-3x)

\int csc^{2} (2 - 3 x) d x

\frac{1}{3} cot (2 - 3 x) + C

Solution steps

\int csc^{2} (2 - 3 x) d x

Apply u-substitution

: \int - \frac{1}{3} csc^{2} (u) d u

= \int - \frac{1}{3} csc^{2} (u) d u

Take the constant out:

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

= - \frac{1}{3} \cdot \int csc^{2} (u) d u

Use the common integral:

\int csc^{2} (u) d u = - cot (u)

= - \frac{1}{3} (- cot (u))

Substitute back

u = 2 - 3 x

= - \frac{1}{3} (- cot (2 - 3 x))

Simplify

= \frac{1}{3} cot (2 - 3 x)

Add a constant to the solution

= \frac{1}{3} cot (2 - 3 x) + C

\int \frac{3 y ^{2}}{( y ^{3} - 12 ) ^{3}} d y

\int sin (2 θ) cos (θ) d θ

\int 14 x ln (7 x) d x

\int \frac{1}{2 x ^{2} - 3 x + 1} d x

\int \frac{cos ( 7 t )}{7 t} d t
