What exactly is it?

 

[acmilan]

the x-coordinate of the xy plane

 

[shafqat]

Usually means x co-ordinate I think.

Thank you.

Would they tell me if I raised my hand and asked that in the HSC exam?

 

[acmilan]

I'd be very surprised if its in the exam at all.

Abcissa and Ordinates. The x and y co-ordinates, respectively.

The actual question is:

If the parabolas y = x² and 2y = (x - a)² intersect at the points P and Q where P is at x = x₁; Q at x = x², show that the abscissa of these points is given by the equation x² + 2ax - a² = 0.

yea that question is like from the 70's.

I have a sheet too from the 70's of locus that uses those 2 words.
That my teacher gave to me cause she said are the best.

You wont get it in the hsc these days.
well they would do this "meets the Abscissa (x-axis) and the ordinate (y-axis)"

Dont worry, the maths hsc is there to test your math knowledge not your vocab. They wouldn't try and dissadvantage people like that.

Try solving them simutaneously cos they r bascially asking the solution to x, which they call '' abcissa''.
