integral of 8cot^4(x)

\int 8 cot^{4} (x) d x

8 (- \frac{1}{3} cot^{3} (x) + x + cot (x)) + C

Solution steps

\int 8 cot^{4} (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8 \cdot \int cot^{4} (x) d x

Apply Integral Reduction

= 8 (- \frac{cot ^{3} ( x )}{3} - \int cot^{2} (x) d x)

\int cot^{2} (x) d x = - x - cot (x)

= 8 (- \frac{cot ^{3} ( x )}{3} - (- x - cot (x)))

Simplify

8 (- \frac{cot ^{3} ( x )}{3} - (- x - cot (x))) : 8 (- \frac{1}{3} cot^{3} (x) + x + cot (x))

= 8 (- \frac{1}{3} cot^{3} (x) + x + cot (x))

Add a constant to the solution

= 8 (- \frac{1}{3} cot^{3} (x) + x + cot (x)) + C

\frac{d}{d x} (x^{\frac{3}{2}} - 1)

\frac{d}{d x} (4 a sec (x) tan (x))

\int \frac{- x}{1 + x ^{4}} d x

y^{^{'}} + y = 2 e^{x}, y (0) = 20

\frac{\partial}{\partial x} (3 x^{y})
