WebMar 24, 2024 · The complex numbers are the field C of numbers of the form x+iy, where x and y are real numbers and i is the imaginary unit equal to the square root of -1, sqrt(-1). When a single letter z=x+iy is used to denote a complex number, it is sometimes called an "affix." In component notation, z=x+iy can be written (x,y). The field of complex numbers … WebIf you want to find out the possible values, the easiest way is probably to go with De Moivre's formula, that is, converting your number into the form r(cos(θ) + isin(θ)), and then you will get (r(cos(θ) + isin(θ)))1 / 2 = ± √r(cos(θ / 2) + isin(θ / 2)).

Web2 Answers. Sorted by: 15. If a complex number z is written as z = a + b i, then Re ( z) = a and Im ( z) = b. (At risk of stating the obvious, "Re" stands for "Real" and "Im" stands for "Imaginary".) If we visualize complex numbers as vectors in R 2, Re is the projection onto the real axis, and Im is onto the imaginary axis.
