A normal distribution with mean zero and standard deviation one
is known as the ['Standard Normal Distribution].
-Given mean [mu][space]and standard deviation [sigma][space]it has the PDF:
+Given mean [mu] and standard deviation [sigma] it has the PDF:
-[space] [equation normal_ref1]
+[equation normal_ref1]
The variation the PDF with its parameters is illustrated
in the following graph:
The cumulative distribution function is given by
-[space] [equation normal_cdf]
+[equation normal_cdf]
and illustrated by this graph

standard deviation /sd/.
-Requires sd > 0, otherwise __domain_error is called.
