### The inverse of the Laplace transform by contour integration
Filed under: Giải tích 7 (MA4247) — Ngô Quốc Anh @ 17:23
Usually, we can find the inverse of the Laplace transform $\mathcal L[\cdot](s)$ by looking it up in a table. In this entry, we show an alternative method that... | {} |

# Collections
Rant's variable system has 4 collection types: list, map, string, and range.
## List
The list type represents a mutable, resizable, ordered collection of zero or more values.
Lists are initialized using a pair of parentheses containing the list elements, separated by semicolons:

In 1787 Fourier decided to train for the priesthood and entered the Benedictine abbey of St Benoit-sur-Loire. When played, the sounds of the notes of the chord mix together and form a sound wave. the Laplace transform is 1 /s, but the imaginary axis is not in the ROC, and therefore the Fourier transform is not 1 /jω in... | {} |
