How to graph an ellipse & determine important characteristics

Learn how to graph horizontal ellipse not centered at the origin. A horizontal ellipse is an ellipse which major axis is horizontal. To graph a horizontal ellipse, we first identify some of the properties of the ellipse including the major radius (a) and the minor radius (b) and the center. These properties enables us to graph the ellipse.

You are a life saver. I have my Precalc final tomorrow and my teacher didn't teach us conics properly and your videos have really helped me prep. Thank you!

I was confused about how to know when it’s vertical or horizontal, now I know thank u

This is the most helpful video in the world bro. you deserve the sub.

Hi sir McLogan, i watched some other videos involving ellipses from your channel, in the other video of yours, you said that the relation of a, b and c is a^2 =b^2 + c^2. And in this video that the relation of a, b and c is c^2 = a^2 - b^2.
Which relation shoud i use? Hoping for your answer, Thank you sir McLogan.

Before watching this I didn't even know what to do with 1 question and after watching I did it effortlessly

Teacher you're wrong the foci should be in decimal form that should be 2.24 yet there is no square root of 5 but in decimal there is. Also the vertices should be V1=(2, 4) V2=(2, -2)
And the co vertices should be CV1=(4, 1) CV2=(0, 1).
And that is not horizontal that is vertical. Just sayin and sharing my thoughts or opinion. But all over I always watch your videos and it helps me alot. Thank you.

Vertical not horizontal the major axis is 9 in which located below the X axis. So it should be vertical nt horizontal.
