what professions use imaginary numbers
Complex numbers have both a real number element and an imaginary number element, usually in the form a + bi. In this form, a and b are real numbers, while i is an imaginary number. An imaginary number is the designation given for the square root of negative one. Many careers that employ higher mathematics also use complex numbers, which can help simplify mathematical equations that would otherwise be much longer.
Economists use complex numbers in order to make profit predictions. When analyzing business cycles, complex numbers can also come into play. Complex numbers may also help an economist trying to determine the internal rate of return, such as the yield on a bond, or an economic duration.
