laplacetransform 2e^{-2t}

laplace transform

2 e^{- 2 t}

\frac{2}{s + 2}

Solution steps

L {2 e^{- 2 t}}

Use the constant multiplication property of Laplace Transform:

For function

f (t)

and constant

a : L {a \cdot f (t)} = a \cdot L {f (t)}

= 2 L {e^{- 2 t}}

L {e^{- 2 t}} : \frac{1}{s + 2}

= 2 \cdot \frac{1}{s + 2}

Refine

2 \frac{1}{s + 2} : \frac{2}{s + 2}

= \frac{2}{s + 2}

f (x) = arctan (x^{3})

\int \frac{1}{3 u} d u

\int \frac{- 6}{x} d x

e x p an d 4 x^{2} (3 x^{3} - 2 x^{2} + 5 x)

\int (7 x^{2} - 4)^{2} x^{3} d x
