Hi.
I am using Mathematica 4.0
I can't find a function that would find arguments of the function.
For example I have an equation: 
y[t+3]=a1* Cos[Sin[u[t+2]]]/Tan[u[t+1]]-Cot[u[t+3]]+a2

and I would like to get those argumets u[t+3], u[t+2], u[t+1]
and give them new values
for example:

x1=u[t+3]
x2=u[t+2]
x3=u[t+1]

and then print that equation with new values:
y[t+3]=a1* Cos[Sin[x2]]/Tan[x3]-Cot[x1]+a2

Can you tell me how to do that?
Thank you.
