# FP1 question Watch

1. In part b, what does parameter mean in this question?
2. The curve is defined through, not only x and y, but parametrically through another parameter t, so the point is a general point on the curve for different values of t. Just substitute the t value into that to find the coordinates and then work from there. It's covered more in C4.

In part b, what does parameter mean in this question?
In this case, parameter just means the value that you put in to find your x and y co-ordinates.

For example, if we had x=at^2, y=2at then t is the parameter and putting in t=some number, eg 3, gives you the co-ordinates, which in that case would be (9a,6a) where you know what a is.
