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

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

1 - e^{x}

\frac{\partial}{\partial x} (\frac{2 x y ^{2}}{4 + x ^{2} y ^{2}})

x \to 0 + lim (\frac{e ^{- \frac{1}{x}}}{x})

x \to - 2 lim (∣ x ∣)
