imaginary numbers with different units

[fahmed-2]

Hello,

I have a question regarding my work. In my file, if I define the units of "lambda" as per "m" then the values of phi have some negative values but if I define the "lambda" as per "cm" then I do not have any negative values of phi. Please help me out about the issue as to why it causes this positive and negative issues only for changing the units. My Mathcad version is prime 4.0.

Thank you,

Faisal

If you multiply the result of the calculation of Lambda with 1/cm instead of 1/m, this has the same effect as multiplying the former values of Lambda by 100.

Why do you expect the same results if you use  different values for Lambda?

BTW, its easier to define   Total.guess:=rows(x.guess), rather than using    last(x.guess).
