Hi all. Need help. So, I have to convert phasor to polar form, and polar form to phasor. In this forum I found good topic about that, how to convert phasor to polar form ( https://forum.allaboutcircuits.com/threads/converting-phasor-to-polar-form.51561/ ). But still cant find a good topic about, how to convert polar form to phasor.
For example:



How they to that?

 

R*exp(j*Phi)=R*cos(Phi)+j*R*sin(Phi)

 

R*exp(j*Phi)=R*cos(Phi)+j*R*sin(Phi)

Thanks

 

Also:

\(R\;=\;\sqrt{(R cos(\phi))^2+(R sin(\phi))^2}\)

and

\(\phi\;=\;tan^{-1}\left(\frac{R sin(\phi)}{R cos(\phi)}\right)\)
