-5+i/2i

**Damon**, Thursday, December 19, 2013 at 3:30pmI suspect you may mean

(-5 +i)/(2i)

be careful about what is numerator and what is denominator when typing.

If my guess is correct then multiply top and bottom by i

(-5 i + i*i) / (2i*i)

But

i * i = i^2 = -1

so

(-5 i - 1) /-2

which is

1/2 + (5/2)i
