BASETHETA (Theta)

• is the angle value.

## Description

• This function shows the Base theta value.
• The basic theta function is defined to be the function  :  given by
• The function   depends on   .
• So for each   with   we get a (not necessarily different) basic theta function.
• Hence there is a whole family of basic theta functions  ,Im  .
• But here we assume   to be fixed, so we have only one basic theta function.
• The basic theta function is quasi-periodic.
• Base Theta is locally uniformly unordered convergent also basic theta function is an entire function.

## Examples

1. BASETHETA(45) = 1.0177028497428964
2. BASETHETA(90) = 2.0354056994857928
3. BASETHETA(8640) = 0.6202026280698192
