    Transform Rectangular notation into still rectangle but with exponential

    Hi! My teacher wrote the following equivalence: If you can not see the image, the equivalence is as follows: (1.10^-3 ) . 10 . [ (j.500)/ (j+1)] x [e^(0.j)] = 3,5 . e^0,70.j I think he transformed from the form: a+b.j into |z|.e^(j.theta) which is equal to [Square root(a^2 +b^2)] ...
