A number with the letter ” j ” in front of it identifies it as an imaginary number in the complex plane. By definition, the j-operator j ≡ √-1; Imaginary numbers can be added, subtracted, multiplied …

As an imaginary unit, use i or j (in electrical engineering), which satisfies the basic equation i 2 = −1 or j 2 = −1. The calculator also converts a complex number into angle notation (phasor …

`(sqrta)^2 = a`, for any value of `a`. and `j = sqrt(-1)` Using these, we can derive the following: `j^2 = (sqrt-1)^2 = -1` Multiplying by `j` again gives us: `j^3 = j^2(j) = -j` Continuing the process …
