Hi all. I am currently trying to find the first few terms of a sine expansion of
q(t)= (A+B*cn(t,m))/(C+D*cn(t,m))
where m is the modulus and cn is the jacobic elliptic cnoidal function and A,B,C,D real and C>D implying no poles. I realize that I should start with a simpler problem. Do some of you have any hints for the sinusoidal version:
q(t) = (A+B cos(t))/(C+D cos(t))
How do I handle this sinusoid term in the denominator?
