integral from 0 to infinity of 6e^{-2x}

\int_{0}^{\infty} 6 e^{- 2 x} d x

3

Solution steps

\int_{0}^{\infty} 6 e^{- 2 x} d x

Compute the indefinite integral:

\int 6 e^{- 2 x} d x = - 3 e^{- 2 x} + C

Compute the boundaries:

\int_{0}^{\infty} 6 e^{- 2 x} d x = 0 - (- 3)

= 0 - (- 3)

Simplify

= 3

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

x \to 0 lim (\frac{x ^{- 2}}{x})

\int \frac{x ^{7} + 2}{( x ^{2} + x + 1 ) ^{2}} d x

\frac{d y}{d x} = \frac{cos ( 20 x )}{e ^{20 y}}

\int t sin (t^{2}) cos (t^{2}) d t
