Animation on basic shapes. Watch FIRST to get the idea prior to trying to understanding the math
only from 1:45 to 3:07 no worries after that!
-----------------------------------------------------------------------------------------------------------------------
Part 1)
equations of an ellipse
translating an ellipse
focus of an ellipse
eccentricity of an ellipse
explanation applet
perimeter of an ellipse
area
Latus R of an ellipse Latus R of a parabola
Work SHEET A worksheet for writing equations of ellipses try #1,3,5,7,9,17,26
All Work Shown HERE for those examples :)
WORK SHEET B worksheet with practice problems and solutions try #MOST..and DEFINITELY the LAST (4)...
17,18,19,20!!!
Click for the work done out for #17-20
and remember....CIRCLES are types of an ellipse. ANYTHING CIRCLE related is fair game!

Part 2)
#2 Another practice for Application problems
Solutions For #2 HERE
----------------------------------------------------------
(Part 3)
Parabolas
focus "rule"
do not worry about parabolic inverses for either ( a sideways parabola)
-------------------------------------------------------
worksheet only try #1,4,5 work done out for #5 to get you started!
