# P5/parametric integration watch

1. 1-a curve is defined by the parametric equations;
x=(t-1)^2, y=(2-t)^3,t greater/equal to 1
Find the area of the region bounded by the x-axis and the part of the curve above the x-axis

2- Find a value for the parameter for the given point
x=t^2, y-=2t p(4,4) m(1,-2)
thx

how much can you do?
3. dont u have to integrate y.dx/dt with respect to t then times by pi and stick in the limits.

I don't know about the pi, but would i have to sketch the curve before deciding upon the limits??
5. No just use the fact that t>0 and y = 0 when the curve crosses the x-axis to get the lower and upper limits
6. That's what i was trying to say...
