integral of 2/x-3/(x^4)

\int \frac{2}{x} - \frac{3}{x ^{4}} d x

2 ln ∣ x ∣ + \frac{1}{x ^{3}} + C

Solution steps

\int \frac{2}{x} - \frac{3}{x ^{4}} d x

Apply the Sum Rule:

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

= \int \frac{2}{x} d x - \int \frac{3}{x ^{4}} d x

\int \frac{2}{x} d x = 2 ln ∣ x ∣

\int \frac{3}{x ^{4}} d x = - \frac{1}{x ^{3}}

= 2 ln ∣ x ∣ - (- \frac{1}{x ^{3}})

Simplify

= 2 ln ∣ x ∣ + \frac{1}{x ^{3}}

Add a constant to the solution

= 2 ln ∣ x ∣ + \frac{1}{x ^{3}} + C

\frac{d}{d x} y + 3 y = 0

(5, - 3), (- 1, - 1)

x \to 0 lim (\frac{x - 45}{x - 5})

f (x) = \frac{x ^{2} - 3}{2}

y^{^{'}} = t y^{3}
