integral of (2(csc(t))^2)/(cot(t))

\int \frac{2 ( csc ( t ) ) ^{2}}{cot ( t )} d t

2 ln ∣ tan (t) ∣ + C

Solution steps

\int \frac{2 ( csc ( t ) ) ^{2}}{cot ( t )} d t

Take the constant out:

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

= 2 \cdot \int \frac{( csc ( t ) ) ^{2}}{cot ( t )} d t

Rewrite using trig identities

= 2 \cdot \int \frac{sec ( t )}{sin ( t )} d t

Apply Trigonometric Substitution

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

= 2 \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= 2 ln ∣ u ∣

Substitute back

u = tan (t)

= 2 ln ∣ tan (t) ∣

Add a constant to the solution

= 2 ln ∣ tan (t) ∣ + C

\int (x^{3} + 1)^{- 1} d x

\int \frac{x ( 1 - x ^{2} )}{1 + x ^{4}} d x

\int (9 + tan^{2} (x)) d x

\int \frac{x}{( x ^{3} + 1 )} d x

\int arcsin (3 t) d t
