integral of 3/x+5/(x^2)

\int \frac{3}{x} + \frac{5}{x ^{2}} d x

3 ln ∣ x ∣ - \frac{5}{x} + C

Solution steps

\int \frac{3}{x} + \frac{5}{x ^{2}} 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{3}{x} d x + \int \frac{5}{x ^{2}} d x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

\int \frac{5}{x ^{2}} d x = - \frac{5}{x}

= 3 ln ∣ x ∣ - \frac{5}{x}

Add a constant to the solution

= 3 ln ∣ x ∣ - \frac{5}{x} + C

\int e^{i 2 t} d t

\int tan^{4} (2 x) sec (2 x) d x

\int \frac{6 x ^{2} + x + 16}{( x ^{2} + 3 ) ( x - 2 )} d x

\int (\frac{6 + x ^{2}}{x}) d x

\int tan (x) + sec^{2} (x) d x
