Hi all 

I am doing a calculation of RLC circuit in MathCAD, but I am facing to a problem with usage of "i" ( notation of complex number) as shown bellow:

Hi. In Mathcad imaginary unit is 1i or 1j, but shows just i or j.

 

Best regards.

Alvaro.

    Works for me if I define j  as the square root of -1

    In real Mathcad (=MC15 and below) I would strongly advise against doing so, but in Prime I have to admit that the imaginary unit displayed as 1j or 1i simply looks too ugly and so I understand that defining j:=1i or something like that makes sense.

      Yes, in "Real" Mathcad 🙂 I'll never assimilate the Primes. I have always defined the imaginary constant explicitly, as it gives me the confidence that I'm using the values I want. Why do you think this is bad practice?
