assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt find dy/dt when x=9 given that dx/dt=9

No one has answered this question because I don't think that there is enough information.

Yep, ur right. Why isnt anyone answering my question!!!!

Like I said, I don't think there is enough information.

Dear guest:

Is there another part to this problem?? We would have to know what the functions x and y were to be able to differentiate anything - and for sure before we just "plugged" "9'" into "thin air.' I have a feeling that this might be a problem dealing with parametric equations, but that's just a guess. See if you can find anymore info.........
