Graphing Ellipses & Circles

I introduce the 4 conic sections, explain the basic structure of Ellipses & Circles, and finish by working through three graphing examples after putting these equations in standard form.

Received a 1.75 in my analytic geometry 3 years ago when i listened to your videos. Now I have graduated BS EE and I'm back to review for my board exams thank you so much ProfRobBob :) your awesome

Please don't stop teaching. You are the best.

I have an Indian professor, and the accent and grammar less than facilitates communication shall we say. Thank you, this was very informative.

The thing with your videos is that... IT IS NOT BORING.... IT'S COMPREHENSIVE... I'm Filipino and I share your videos to my continue sir! God Bless

[Baleion]

Thank you again for taking the time and effort to present high quality lessons online.  I watch your videos just about every day. Top notch!

My math teacher believes in "productive struggling" aka he doesn't show us how to do anything step-by-step. This video helped me learn so much! Thank you and I'm definitely recommending your channel to my friends!!!!

[profrobbob]

WOW...you are sure making me proud by watching all these videos!!!

Once again, being the best at what you do! Thanks, Mr. Tarrou! Curiously, I found that working with ellipses was not as difficult as I originally thought. I could do all my exercises and even found an equation for the orbit of the Earth around the Sun. Nothing beats that nerdy feeling!

[profrobbob]

I don't think I have done a video with that example...but you plug each of your thee points into the general form to set up three equations. Then you can use matrices with either the Gaussian Elimination Method or Determinants to solve for D E and F. I have videos for solving three variable systems. There are other methods of solving but I don't have videos for those. I hope this helps.

You're welcome and THANK YOU for watching and subscribing all the way from the Philippines!

Prof. Rob, you sir are a scholar and a gentleman!!!!Thanks much.

[profrobbob]

I wish I could be more help here:( I don't recall off the top of my head dealing with these types of problems in my class. Thank you for subscribing. I appreciate the support very much.

[aarond]

Thanks for making this video! It's nice to see someone slow down and teach things the right way. You just earned another subscriber. BAM!!!

[brandonchao]

First and foremost "THANK YOU" for this video. Without this video, I don't think I would of grasp the "Conics". This is however is the last exam of my semester and it is covering conics and equations and I thank you for this video.

[profrobbob]

For a second I thought you were my cousin...she loves to dress her cats:)
Thank you for this extraordinary compliment! And yes I have heard the words before, but I never get tired of hearing how much these videos are benefitting people "everywhere", in ll walks of life...it's really still quite AMAZING!!! Building my channel has now become like a second job for both myself and my wife. We hope the saying stands true "Build It, And They Will Come!" THANK YOU from us both:))

[pablo-sjcc]

Well, 32 minutes 33 seconds well spent. Thank you sir! 

[profrobbob]

No I don't, but if you go the homepage of my channel you can use the magnifying glass under my banner to search just my channel. I can tell the way YouTube is working for me, Google is doing some kind of updates or something as well. It keeps changing my login to another Google + account I don't use for my math channel:/ Thank you for watching and your support though:D

[peevestheprefect]

Thank you so much for all the videos you've been making! When I don't understand something in class I know that I have these videos to help me. Learning from your videos actually makes me enjoy doing math, which is extraordinary considering how much I've despised it in the past! You also have helped me get the A's that I've earned in class, so thank you very much for your videos.

[barperetz]

Your videos are amazing i wish you could be my math teacher. You have got me through every sigle test the past 2 quarters. Only if I had known you before... Thanks a lot

Going through your conic sections, they are very helpful. The first time we were introduced to them, we were literally handed worksheets and told to study them and do example problems on our own. It was terribly confusing. But this clears it up. :)

Fun story, a kid in my class would pronounce "foci" as "fo-chi" and while it annoyed the heck out of me, it would make me laugh all the time. Thanks again!
