integral of 7cot^3(x)csc^3(x)

\int 7 cot^{3} (x) csc^{3} (x) d x

- 7 (\frac{1}{5} csc^{5} (x) - \frac{1}{3} csc^{3} (x)) + C

Solution steps

\int 7 cot^{3} (x) csc^{3} (x) d x

Take the constant out:

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

= 7 \cdot \int cot^{3} (x) csc^{3} (x) d x

Apply u-substitution

: \int - u^{2} (u^{2} - 1) d u

= 7 \cdot \int - u^{2} (u^{2} - 1) d u

Take the constant out:

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

= 7 (- \int u^{2} (u^{2} - 1) d u)

Expand

u^{2} (u^{2} - 1) : u^{4} - u^{2}

= 7 (- \int u^{4} - u^{2} d u)

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 7 (- (\int u^{4} d u - \int u^{2} d u))

\int u^{4} d u = \frac{u ^{5}}{5}

\int u^{2} d u = \frac{u ^{3}}{3}

= 7 (- (\frac{u ^{5}}{5} - \frac{u ^{3}}{3}))

Substitute back

u = csc (x)

= 7 (- (\frac{csc ^{5} ( x )}{5} - \frac{csc ^{3} ( x )}{3}))

Simplify

7 (- (\frac{csc ^{5} ( x )}{5} - \frac{csc ^{3} ( x )}{3})) : - 7 (\frac{1}{5} csc^{5} (x) - \frac{1}{3} csc^{3} (x))

= - 7 (\frac{1}{5} csc^{5} (x) - \frac{1}{3} csc^{3} (x))

Add a constant to the solution

= - 7 (\frac{1}{5} csc^{5} (x) - \frac{1}{3} csc^{3} (x)) + C

f (y) = e^{3 y}

n = 0 \sum \infty 1 (n + 1)

\frac{d}{d x} (2 x csc (x) sec (x))

(2, 3), (6, - 5)

\int y (- 4 y - 1) d y
