Hi, In the context of the philosophy of science are the statements E=IxR and x=f(y) equivalent? or are their implications, as far as positive expressions of truth, equivalent? Thanks, David

x=f(y) is a general scheme for any two-variable function (well, technically "relation", but we're typically interested in functions; i.e., one-to-one relations from x to y). E=IxR, by contrast, appears to have three variables rather than two (unless E, I or R are constants), so the approrpiate general schema would be x=f(y,z) rather than x=f(y). In this particular case, the function f is the product of the (values of the) two variables over which it operates.
