Hello

Now I know that a circle isnt a function but buy using

y=(r^2-x^2)^0.5 and y=-(r^2-x^2)^0.5 one can be drawn on a graphing program.

Is there a way to do a similar thing but with an oval or ellipse (I want the ellipse to be vertical not horizontal)

x2 y2

-- + --- = 1

a2 b2

is all I could find relating to the graph of an ellipse but I am looking for something that has y=............ so I can enter it into the graphing program

Thank you!
