What is the integral of e^xcos(e^x)+(2x+2)/(x^2+2x) ?

The integral of e^xcos(e^x)+(2x+2)/(x^2+2x) is sin(e^x)+ln|x+2|+ln|x|+C

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

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

sin (e^{x}) + ln ∣ x + 2 ∣ + ln ∣ x ∣ + C

Solution steps

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

\int e^{x} cos (e^{x}) d x = sin (e^{x})

\int \frac{2 x + 2}{x ^{2} + 2 x} d x = ln ∣ x + 2 ∣ + ln ∣ x ∣

= sin (e^{x}) + ln ∣ x + 2 ∣ + ln ∣ x ∣

Add a constant to the solution

= sin (e^{x}) + ln ∣ x + 2 ∣ + ln ∣ x ∣ + C

\int - 6 e^{t} + 3 e^{3 t} d t

\int (7^{3} + 6 x^{2} - 9 x - 8) d x

\int sec^{n} (d) x d x

\int x e^{(- 5 x)} d x

\int (3 - 18 x^{2}) csc^{2} (2 x^{3} - x) d x
