Thank you for your suggestion! I really appreciate it! :)
Okay so I calculated \frac{dx}{dt} and \frac{dy}{dt}.
[SIZE="4"]\frac{dx}{dt} = -\frac{\frac{∂F}{∂t}}{\frac{∂F}{∂x}} and [SIZE="4"]\frac{dy}{dt} = -\frac{\frac{∂F}{∂t}}{\frac{∂F}{∂y}}
I substituted x and y into the two different...
I cannot figure out how to do this problem completely:
If U =x3y, find \frac{dU}{dt} if x5 + y = t and x2 + y3 = t2.
I know that I am using the chain rule here and I have the partial derivates of U:
\frac{∂U}{∂x} = 3x2y
\frac{∂U}{∂y} = x3
So far I have the equation given below...
