Conic Sections

















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)

#1 Application examples with solutions


#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!
