Firstly I do apologise, because this question is got more to do with the mathematical side of Electronic Engineering, because my mathematical classification is not that good I don't know where I would put this question on the mathematics section, if any of the moderators or whoever can, wants to move it there, I do apologise.(adsbygoogle = window.adsbygoogle || []).push({});

I am having a bit of problem with my calculator, unlike many other people in my class, my calculator can't exchange complex numbers to polar form, so I have to do it by using some mathematics.

I know how to change from polar form back to complex notation, so for example imagine a voltage of 6.08 |51.8*.

I believe that 6.08cos51.8 will get you the real component and 6.08sin51.8 is J, so in J-notation ==> 6.08 |51.8* = 3.76 + J4.78

I haven't made up these difficult numbers, but I have taken them from a class example, I suppose the method is correct because that was the answer checked by the teacher.

However I do not know how to exchange a number back to polar form, I think my best option would be buying a better calculator, but I would appreciate if someone could show me by mathematical terms, Thank You.
