Question:Calculating derivatives

Hello there,

i got a question regarding derivatives in Matlab.

 

I got a function for a example:

f:=f1(y)*f2(x)

 

from this function i need the partial derivatives with respect to x and y, i can easily get them with

diff(f,x)

diff(f,y)

 

now i want to compute the derivative of f with respect to time t, assuming that y and x both depend on t - how can i tell maple that y and x depend on t?

 

thanks

ben
