[issue46444] Wrong value of pi for larger values using math.cos() function

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

Arguments of cos() and sin() should be in radians, not in degrees. So the correct formulas are k*cos(pi/2-pi/k) and k*sin(pi/k). They are useless because to find the pi approximation you need to know pi.
