Working with delayed functions and non-delayed functions with Mathcad Prime 9.

[gatlas]

How do work with several functions one would be f(t) and another would be g(t-tau)?

Mathcad Prime 9 doesn't let me use a delay.

Any suggestions?

This just worked: Make one function f(t) and another function g(t,tau). Note that tau is a constant.

I can then add both functions.

I see no problem here.

Can you show in more detail what you tried and where Prime would had refused to do what you did.

Instead of defining separate functions, you may also call/evaluate a function by providing the delay in the call:
