I am to find the values when z = i and z = (5 - 2i)/(2 - i)
I am totally confused by the Re and Im. Since if z is real how can it be equal to i or anything with i in it????
If I put i/i and then to clear i out of denominator I multiple by -i/-i then I get - i^2/ -i^2 which is 1. I know I am making a mistake because the answer is suppose to be 0. Is that because the numerator has to be 0 since z = i is not real???
If I use the other value for z I should get a value of 12 but again, I get 1 so I am not understanding the question. Any assistance would be much appreciated. Frostking
