A fancy range is really a range that may be expressed in the form (a + bi) exactly where a and b are true numbers, and i is a solution on the equation x2 = −1. Since no genuine amount satisfies this equation, i is referred to as an imaginary range. Intricate numbers have a real component and an imaginary section.
