EllipticNomeQ
 Usage
Notes
 Further Examples
Certain elliptic functions, such as the theta functions, traditionally use the nome  as their argument; others use the modulus  . EllipticNomeQ returns the nome corresponding to a given modulus. This is the definition:
In[1]:=
|
Out[1]=
|
This is the derivative.
In[2]:=
|
Out[2]=
|
As  approaches 1 from below along the real line,  approaches 1 very abruptly. In order to obtain meaningful values for the function in the neighborhood of 1, it is a good idea to use multiple precision.
In[3]:=
|
Out[3]=
|
There is a branch cut along the ray  .
In[4]:=
|
Out[4]=
|
This shows approximately the range of EllipticNomeQ inside the unit circle.
In[5]:=
