WebThe principal square root is always the positive root. For example, the principal root of sqrt(9) = 3. But, sqrt(9) has 2 roots. If both roots are needed, usually when solving quadratic equations, then the +/- notation is used as a shorthand for saying we need +sqrt(9) = 3 and … WebTo find a square root of a given complex number z, you first want to find a complex number w which has half the argument of z (since squaring doubles the argument). Compute r = z and let w = z + r; thus w lies r steps to the right of z in the complex plane. Draw a picture of this, and it should be clear that the points 0, z and w form an ...

WebUnit Imaginary Number. The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √ (−1) is i for imaginary. But in electronics the symbol is j, because i is used for current, and j is next in the alphabet.
