integral of (e^{-x}-e^2)(e^x+e^{-5})

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

\frac{- 1 + e ^{3}}{e ^{3}} x - e^{- x - 5} - e^{x + 2} + C

Solution steps

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

Expand

(e^{- x} - e^{2}) (e^{x} + e^{- 5}) : 1 + e^{- x - 5} - e^{2 + x} - \frac{1}{e ^{3}}

= \int 1 + e^{- x - 5} - e^{2 + x} - \frac{1}{e ^{3}} 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 e^{- x - 5} d x - \int e^{2 + x} d x - \int \frac{1}{e ^{3}} d x

\int 1 d x = x

\int e^{- x - 5} d x = - e^{- x - 5}

\int e^{2 + x} d x = e^{2 + x}

\int \frac{1}{e ^{3}} d x = \frac{1}{e ^{3}} x

= x - e^{- x - 5} - e^{2 + x} - \frac{1}{e ^{3}} x

Simplify

x - e^{- x - 5} - e^{2 + x} - \frac{1}{e ^{3}} x : \frac{- 1 + e ^{3}}{e ^{3}} x - e^{- x - 5} - e^{x + 2}

= \frac{- 1 + e ^{3}}{e ^{3}} x - e^{- x - 5} - e^{x + 2}

Add a constant to the solution

= \frac{- 1 + e ^{3}}{e ^{3}} x - e^{- x - 5} - e^{x + 2} + C

\frac{\partial}{\partial x} (x e^{x y} - 2 y)

7 x e^{x} csc (x)

\int 2 x ln (x) d x

\int \frac{8 x - 3}{x ^{2} + x + 1} d x

x \to 0 + lim (\frac{∣ x ∣}{x})
