Expression As A Ratio of Polynomials
For even orders, the elliptic rational functions may be expressed as a ratio of two polynomials, both of order n.
- (for n even)
where are the zeroes and are the poles, and is a normalizing constant chosen such that . The above form would be true for odd orders as well except that for odd orders, there will be a pole at x=∞ and a zero at x=0 so that the above form must be modified to read:
- (for n odd)

Famous quotes containing the words expression and/or ratio:
“Parents do not give up their children to strangers lightly. They wait in uncertain anticipation for an expression of awareness and interest in their children that is as genuine as their own. They are subject to ambivalent feelings of trust and competitiveness toward a teacher their child loves and to feelings of resentment and anger when their child suffers at her hands. They place high hopes in their children and struggle with themselves to cope with their children’s failures.”
—Dorothy H. Cohen (20th century)
“People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.”
—Samuel Butler (1835–1902)
