The problem states that there is a glen described by the hyperboloid Z = X^2 - 2Y^2 and defined over [-2,1]x[0,2]. An object follows the course defined by X(t) = cos(t)cos(2t) and Y(t) = sin(t)cos(2t).
I have to compute the rate of change of the elevation of the object with respect to time at arbitrary time t.
I graphed the function and found the critical points, saddle points, local/absolute max/mins etc.., then i graphed the course parametrically and it resembled a four-leafed rose.
rate of change makes me think of taking the derivative, but course makes me think of integration. which direction should i take? vague replies only please (as always) :)
