## What is the equation for an ellipse?

The equation of an ellipse written in the form (x−h)2a2+(y−k)2b2=1. The center is (h,k) and the larger of a and b is the major radius and the smaller is the minor radius. The equation of an ellipse written in the form px2+qy2+cx+dy+e=0 where p,q>0.

## What is perfect ellipse?

Perfect ellipse formula L and H are the length and height of the desired ellipse. Plug the numbers into the formula, and you get D = 12-1/2. Draw a straight line exactly 16 in. long and mark the center point. Mark 6-1/4 in.

## What is Trammel method?

A trammel is an impediment to freedom or motion. By placing some geometric restrictions on the motion of a pen or pencil, specific types of figures can be drawn. The trammel method is one of many ways to apply this principle to the construction of ellipses (circles and ovals).
