integral of csc^4(x)cot^6(x)

\int csc^{4} (x) cot^{6} (x) d x

- \frac{1}{7} cot^{7} (x) - \frac{1}{9} cot^{9} (x) + C

Solution steps

\int csc^{4} (x) cot^{6} (x) d x

Apply u-substitution

: \int - u^{6} (1 + u^{2}) d u

= \int - u^{6} (1 + u^{2}) d u

Take the constant out:

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

= - \int u^{6} (1 + u^{2}) d u

Expand

u^{6} (1 + u^{2}) : u^{6} + u^{8}

= - \int u^{6} + u^{8} 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

= - (\int u^{6} d u + \int u^{8} d u)

\int u^{6} d u = \frac{u ^{7}}{7}

\int u^{8} d u = \frac{u ^{9}}{9}

= - (\frac{u ^{7}}{7} + \frac{u ^{9}}{9})

Substitute back

u = cot (x)

= - (\frac{cot ^{7} ( x )}{7} + \frac{cot ^{9} ( x )}{9})

Simplify

- (\frac{cot ^{7} ( x )}{7} + \frac{cot ^{9} ( x )}{9}) : - \frac{1}{7} cot^{7} (x) - \frac{1}{9} cot^{9} (x)

= - \frac{1}{7} cot^{7} (x) - \frac{1}{9} cot^{9} (x)

Add a constant to the solution

= - \frac{1}{7} cot^{7} (x) - \frac{1}{9} cot^{9} (x) + C

\int sin (x) ln (x) d x

f (x) = \frac{9}{t}

\frac{d y}{d x}, 25 x^{2} - 10 x y + 4 y^{2} = 100

\int \frac{( x ^{3} )}{9 - x ^{2}} d x

\frac{d ^{2}}{d x ^{2}} (x^{e^{x}})
