integral of csc^4(θ)

\int csc^{4} (θ) d θ

- \frac{1}{3} csc^{3} (θ) cos (θ) - \frac{2}{3} cot (θ) + C

Solution steps

\int csc^{4} (θ) d θ

Apply Integral Reduction

= - \frac{cos ( θ ) csc ^{3} ( θ )}{3} + \frac{2}{3} \cdot \int csc^{2} (θ) d θ

\int csc^{2} (θ) d θ = - cot (θ)

= - \frac{cos ( θ ) csc ^{3} ( θ )}{3} + \frac{2}{3} (- cot (θ))

Simplify

- \frac{cos ( θ ) csc ^{3} ( θ )}{3} + \frac{2}{3} (- cot (θ)) : - \frac{1}{3} csc^{3} (θ) cos (θ) - \frac{2}{3} cot (θ)

= - \frac{1}{3} csc^{3} (θ) cos (θ) - \frac{2}{3} cot (θ)

Add a constant to the solution

= - \frac{1}{3} csc^{3} (θ) cos (θ) - \frac{2}{3} cot (θ) + C

\frac{d}{d x} (∣ x + 3 ∣)

f^{^{'}} (x) = \frac{1}{3} x^{4} - 5 x^{2} + 5

y = ln (\frac{1}{x})

\frac{d}{d x} (\frac{tan ( x )}{1 - sec ( x )})

x e^{x} - e^{x}
