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

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

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

Solution steps

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

Simplify

\frac{sin ( x )}{sin ^{2} ( x )} : csc (x)

= \int csc (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 = tan (\frac{x}{2})

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

Add a constant to the solution

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

\int \frac{3 x + 1}{x ^{2} + 2 x + 5} d x

\int 2^{3 - x} d x

\int (5 x^{2} - 8 x + 5) d x

\int 5 arctan (4 x) d x

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