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

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

2 ln ∣ tan (x) ∣ + C

Solution steps

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

Take the constant out:

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

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

Rewrite using trig identities

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

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 (x)

= 2 ln ∣ tan (x) ∣

Add a constant to the solution

= 2 ln ∣ tan (x) ∣ + C

\int_{0}^{3} 3 e^{x} d x

\int \frac{6}{( 9 x ^{2} + 1 ) ^{2}} d x

y = \frac{arctan ( 2 x )}{x}

x \to 0 lim ((x + 1)^{l n (x)})

f (x) = 9 + 5 x^{2} - 2 x^{3}
