integral of (e^x+4)/(e^x)

\int \frac{e ^{x} + 4}{e ^{x}} d x

x - \frac{4}{e ^{x}} + C

Solution steps

\int \frac{e ^{x} + 4}{e ^{x}} d x

Expand

\frac{e ^{x} + 4}{e ^{x}} : 1 + \frac{4}{e ^{x}}

= \int 1 + \frac{4}{e ^{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 1 d x + \int \frac{4}{e ^{x}} d x

\int 1 d x = x

\int \frac{4}{e ^{x}} d x = - \frac{4}{e ^{x}}

= x - \frac{4}{e ^{x}}

Add a constant to the solution

= x - \frac{4}{e ^{x}} + C

\int \frac{3 x + 1}{x} d x

\int \frac{- cos ( x )}{sin ( x )} d x

\int \frac{x ^{8}}{x ^{9} - 1} d x

\int (3 x^{5} - 8 x^{3} + 2) d x

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