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

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

ln ∣ x ∣ + x + C

Solution steps

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

Expand

\frac{x + x ^{2}}{x ^{2}} : \frac{1}{x} + 1

= \int \frac{1}{x} + 1 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{1}{x} d x + \int 1 d x

\int \frac{1}{x} d x = ln ∣ x ∣

\int 1 d x = x

= ln ∣ x ∣ + x

Add a constant to the solution

= ln ∣ x ∣ + x + C

\int 1 - cos (θ) d θ

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

\int - 3 x tan (5 x^{2}) d x

\int 11 sin (x) d x

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