Weekly Extra Credit Problem - 2nd try!!
This was last week's problem:
An entry door, measuring 36inches wide and 82 inches high, is to have an oval window installed and the door must be "cut out" to accommodate the window. There must be at least two inches of wood on any side of the window, and the bottom requires four additional inches of space from the window. How can a perfect ellipse be constructed to produce as large of a window as possible? Be specific about exactly where to place your foci and what size of "loop" must be used in tracing out the ellipse.
Revised question: Find the location of the foci and the length of string needed to make an ellipse with a major axis of length 74 inches and a minor axis of length 32 inches.
(this is the answer to last week's question!!)
