integral from 0 to infinity of 2e^{-2x}

\int_{0}^{\infty} 2 e^{- 2 x} d x

1

Solution steps

\int_{0}^{\infty} 2 e^{- 2 x} d x

Compute the indefinite integral:

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

Compute the boundaries:

\int_{0}^{\infty} 2 e^{- 2 x} d x = 0 - (- 1)

= 0 - (- 1)

Simplify

= 1

\frac{d y}{d x}, y = 7 x^{8}

\int 3 x - 4 x d x

x \to 3 - lim (\frac{2 x}{x - 3})

x \to 3 lim (lo g_{5} (x))
