Posted by Hannah on Tuesday, February 22, 2011 at 5:24am.

a curve ahs parametric equations x=t^2
and y= 1-1/2t for t>0.

i)find the co-ordinates of the point P where the curve cuts the x-axis which i found to be P(1/4, 0)

the next part i cant do
ii) find the gradient of the curve at this point.

So far, I have the gradient to be:
-2/4t^3

is that gradient right and how do I get the value at the point P.
