Why can I not use mathematic expression with "j" ( complex number) in MathCAD ?

11 November 2018 1 5K Report

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 in my attached file

Please help me to treat this.

Best regards,

Jordan I. Nenkov

The imaginary number is missing. This is the problem.

It is necessary to define the imaginary number as: j:=sqrt(-1) at the begining of document and use the "j" symbol after that (see fixed file as an attachment)

Sqrt symbol is not possible to be entered here. In the MathCAD this symbol is need to be select from calculator menu.

Best Regards
