what are they? i thought they are the y co-ordinates of a point but what do they mean when they say the ordinate of P intersect the asymptote at N or something like that. This is from the blue patel 4U text book.

but what do they mean when they imply the ordinate is a line? eg. "NP is the ordinate of a point P(x<sub>1</sub>,y<sub>1</sub>) on the ellipse b<sup>2</sup>x<sup>2</sup>+a<sup>2</sup>y<sup>2</sup>=a<sup>2</sup>b<sup>2</sup>"Originally posted by Bannanafish
the x value is one ordinate
the y value is another ordinate
together they form a co-ordinate
the abscissa should be the x coordinateOriginally posted by Newbie
whats an absisscae ?
i dont even know the spelling of it
With P(asec@, btan@) and asymptote y=bx/a, N would have coords (atan@, btan@).Originally posted by Constip8edSkunk

Well you can think of it as a line: from the above example, the parametric coords are x=asec@, y=btan@. Here the ordinate is the line y=btan@, so you want to know where y=btan@ intersects y=bx/a.but what do they mean when they imply the ordinate is a line?
