Complex Algebra - Miami

Complex Algebra When the idea of negative numbers was broached a couple of thousand years ago, they were considered suspect, in some sense not real. Later, when probably one of the students of Pythagoras discovered that numbers such as 2 are irrational and cannot be written as a quotient of integers, legends have it that the discoverer suffered dire consequences. Now both negatives and irrationals are taken for granted as ordinary numbers of no special consequence. Why should 1 be any different? Yet it was not until the middle 1800's that Complex numbers were accepted as fully legitimate. Even then, it took the prestige of Gauss to persuade some. How can this be, because the general solution of a quadratic equation had been known for a long time?

Complex Exponentials A function that is central to the analysis of di erential equations and to untold other mathematical ideas: the exponential, the familiar ex. What is this function for complex values of the exponent? ez =ex+iy exeiy (3:4) This means that all that’s necessary is to work out the value for the purely imaginary exponent, and
