integral of+(x^4+12x^2+1)/(x^5+20x^3+5x)

\int + \frac{x ^{4} + 12 x ^{2} + 1}{x ^{5} + 20 x ^{3} + 5 x} d x

\frac{1}{5} ln x^{5} + 20 x^{3} + 5 x + C

Solution steps

\int \frac{x ^{4} + 12 x ^{2} + 1}{x ^{5} + 20 x ^{3} + 5 x} d x

Apply u-substitution

: \int \frac{1}{5 u} d u

= \int \frac{1}{5 u} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{5} ln ∣ u ∣

Substitute back

u = x^{5} + 20 x^{3} + 5 x

= \frac{1}{5} ln x^{5} + 20 x^{3} + 5 x

Add a constant to the solution

= \frac{1}{5} ln x^{5} + 20 x^{3} + 5 x + C

\int 2 e^{x} - 8 x d x

y = \frac{5}{1 + x ^{2}}, (4, 0.29412)

f (x) = 6 x^{2} cot (x)

x \to \infty lim (2 x - 2 x)

\frac{d}{d x} (x^{8} cos (x))
