I want to know how do I declare symbol in maple. Say y=2x+b, I want maple to treat this y as a function of x with b as a constant (or symbol). How should I do that?
More specificaly, I am trying to ask maple to do some calculation for me. and it returns me "Fail". So I am suspecting that maple didn't take other letters as symbol. Here is my code:
with(Statistics); h := RandomVariable(Exponential(H)); simplify(PDF(h, t))
with(Statistics); g := RandomVariable(Exponential(G)); simplify(PDF(g, t))
constants := constants, Ps Pr
but maple return:
