integral of (sin(2x))/(sin^2(x))

\int \frac{sin ( 2 x )}{sin ^{2} ( x )} d x

ln (sin^{2} (x)) + C

Solution steps

\int \frac{sin ( 2 x )}{sin ^{2} ( x )} d x

Apply u-substitution

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

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = sin^{2} (x)

= ln sin^{2} (x)

Apply absolute rule:

x^{2} = x^{2}

, assuming

x \in R

sin^{2} (x) = sin^{2} (x)

= ln (sin^{2} (x))

Add a constant to the solution

= ln (sin^{2} (x)) + C

\frac{\partial}{\partial t} (e^{π t})

n = 1 \sum \infty \frac{n + 1}{n + 2}

x \to 4 lim (\frac{x - 2}{x})

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

\frac{d}{d x} ((3 x - 1)^{5} (1 - 3 x)^{4})
