Both of these need to be put into standard form: .
I'll do the first one . . .
So we have: .
Hello, I have the basics of solving for foci, vertices, eccentricity and graphing ellipses down, but for some reason these two problems have me scratching my head.
x^2+4y^2=1 and y^2=1-2x^2 both of these need to be put into std form which is (x^2\a^2)+(y^2\b^2)=1, before I can solve for anything. Help!
We had: .
It is almost in standard form: the right side is 1, is over
But the "4" should not be next to the , it should be under.
One way to eliminate the 4 is to multiply top and bottom by
If you defined to be the larger of the two numbers, this is correct.
