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

integral

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

- x cot (x) + ln ∣ sin (x) ∣ + C

Solution steps

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

Apply Integration By Parts

: - x cot (x) - \int - cot (x) d x

= - x cot (x) - \int - cot (x) d x

\int - cot (x) d x = - ln ∣ sin (x) ∣

= - x cot (x) - (- ln ∣ sin (x) ∣)

Simplify

= - x cot (x) + ln ∣ sin (x) ∣

Add a constant to the solution

= - x cot (x) + ln ∣ sin (x) ∣ + C

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

\frac{1}{( x - x ^{\frac{1}{2}} )}

e^{- 5} x

x^{\frac{- 1}{2}}

x^{2} 1 + 4 x^{2}
