How would one might parametrize y = x^2
Here is the problem
"an object moves along the parabola y = x^2 from (0,0) to (2,4). One of the forces acting on the object is F(x,y) = (x+2y)i + (2x+y)j. Calculate the work done by F."
the soluction manual has r(t) = ui + u2j -- [0,2]
I forgot how to parametrize this type of function(y = x^2), and how to get the limits of integration of [0,2]?
Thanks
Philip
