So the question that we have before us is to find a real world design that uses an ellipse.
00:06
And then we're supposed to place a coordinate grid over that design and get an equation for it.
00:11
So what i did is i went and found a football, which is an ellipse.
00:15
And i have put a grid over top of it.
00:18
And all we're going to do is we're going to try to get the equation of that ellipse.
00:22
And so what we're going to do is we're going to count out.
00:24
That's one, two, three, four, five, six, seven, eight, nine, and a bit.
00:30
So we're going to say 9 .2 maybe, and it's at minus 9 .2 over here then.
00:37
And then we're going to count up, and it's 1, 2, 3, 4, 5, 6, let's say, and 1, 2, 3, 4, 5, 6 down here.
00:51
So we're going to say roughly that it's x squared over 9 .2 squared plus y squared over 6 squared, is equal to 1...
