**Basically, part of my uni course is electronics and some of the mesh current method questions involve complex numbers, mainly the use of j and other things. I would get the answer as the solution gets it down to 4-j7 and then it says this equals 8.0623<-60.2551° .................................................. ...........< is supposed to be like/_ but couldnt find the proper symbol. I just cant understand the meaning of j and such things. How does it get from 4-j7 to this other answer? Just wondering if anyone could explain the conversions of these symbols to normal numbers and degrees as it is saying the final answer is? can provide full solution if needed.**

Thanks, Andy

Thanks, Andy

I can do the question, and understand most of it, its a solution from a past paper in university, but im having trouble understanding only the complex numbers part, mainly the way in which it changes from j over to a number and degrees? i understand only that j is the sqrt of -1. Any help appreciated! Thanks again! Andy
