In mathematics, the eccentricity, denotit e or , is a parameter associated wi every conic section. It can be thoucht o as a measur o hou much the conic section deviates frae bein circular.
In pairticular,
- The eccentricity o a circle is zero.
Ellipses, hyperbolas wi aw possible eccentricites frae zero tae infinity an a parabola on ane cubic surface. - The eccentricity o an ellipse which is nae a circle is greater nor zero but less nor 1.
- The eccentricity o a parabola is 1.
- The eccentricity o a hyperbola is greater nor 1.
Furthermore, twa conic sections are seemilar if an anly if thay hae the same eccentricity.
