integral of (x^4e^x-6x^3)/(x^4)

\int \frac{x ^{4} e ^{x} - 6 x ^{3}}{x ^{4}} d x

e^{x} - 6 ln ∣ x ∣ + C

Solution steps

\int \frac{x ^{4} e ^{x} - 6 x ^{3}}{x ^{4}} d x

Expand

\frac{x ^{4} e ^{x} - 6 x ^{3}}{x ^{4}} : e^{x} - \frac{6}{x}

= \int e^{x} - \frac{6}{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} d x - \int \frac{6}{x} d x

\int e^{x} d x = e^{x}

\int \frac{6}{x} d x = 6 ln ∣ x ∣

= e^{x} - 6 ln ∣ x ∣

Add a constant to the solution

= e^{x} - 6 ln ∣ x ∣ + C

t an g e n t y = x^{3} + 2, (2, 2)

\frac{\partial}{\partial x} (x y \cdot ln (x + y))

\int \frac{1}{sinh ( x )} d x

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