Parameters aren't seen inside function

You define the circuit using symbols. Numbers are symbols. Some trig functions have been defined as symbols. pi is defined as a symbol, so that would work if you stopped using math.pi.

If you want to use a variable I think you need to define it as a symbol or expression. Take a look at the documentation to see if this is what you want.
