Question

What is the Gaussian function?

Answer 1

Gaussian function is used to solve normal distribution problems.
It is a probability density function (PDF) of normal distribution.

Explanation:

here,
a = 1 / ( `sigma` `sqrt`(2 `pi` ))
`sigma` = standard deviation
`pi` = 3.14159265359
`e` = 2.71828182845
and `c^2` = variance
