My teacher wrote the following equivalence: 1.JPG 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)] . e^[j . arctg(b/a)] I Reduced the first expression (1.10^-3 ) . 10 . [ (j.500)/ (j+1)] x [e^(0.j)] into 5+ 5.j But obviously what gave me does not lead to the desired result: 3,5 . e^0,70.j I don't understand what I can possibly did wrong or if there is another way to get this equivalence. Thank you! Last edited by Paula; December 29th, 2015 at 04:28 PM.
