This is like finding a relic of the past! I so so so so so love this website :heart_eyes: , it\'s like a treasure to behold! Not only does it help with math, but it also has minigames and fun links! I also like how, even now, the author of this website still responds to the guestbook! I would donate if I could, but unfortunately, I currently don\'t possess the financial capacity to do so :pensive: :confounded: . As a first-year college student with poor foundations in math, this is like a godsend! Thank you for creating this site!!!!!!! |

Hello Dr. Burns, I am a 69 year old student and this is my last class other than my Senior Project. I have already had a successful career but always wanted to get my degree. I have had Advanced Math before but it has been a long while. I am trying to relearn Algebra. You have done a great job explaining Algebra. I just keep trying to work the problems until I figure out how it was done. I wish that anyone that ever wanted a degree to let them know it is never too late to accomplish their dream. |

Paraphrasing Pedrotti\'s Optics, it is obvious by Fermat\'s principle and the definition of an ellipse that \"A\" an object placed at one focus of an ellipse will produce an image at the other focus. Also, \"B\", an object placed at one focus of a hyperbola will produce a virtual image at the other focus. Statement A \"is\" obvious based on definition that ellipse is locus of points such that sum of distances from foci to a point on the ellipse is a constant. Statement \"B\" is not the least bit obvious. You do not use Fermat\'s principle. Instead you use angle of incidence equals angle of reflection ... you produce a real image (by using the \"back\") of the hyperboloid and your result is beautiful. Thank you!!! |
