FUNCTIONS OF A COMPLEX VARIABLE - A Course of Mathematics for Engineerings and Scientists, Volume 5 - CHAPTER IIIELSEVIERA Course of Mathematics for Engineerings & Scientists
It’s interesting to visualize functions of a complex variable, even very simple functions likef(z) = 1/z. The previous post looked at what happens totrianglesunder the reciprocal mapw= 1/z. This post will look at the same map applied to a polar grid, then look at the effect a shift...

To make a distinct copy of a complex number, you must call the function with both arguments again or declare another variable with the complex number literal:Python >>> z = complex(3, 2) >>> z is complex(3, 2) False When you provide two arguments to the function, they must always...

In mathematics we show an imaginary number by using the letter i. When simplifying complex numbers, we must remember that a variable multiplied by itself gives us the variable squared. {eq}x*x=x^2 {/eq} This is imperative to remember because when we simplify complex numbers, we will ...

Hence, the formula for multiplying complex numbers with real numbers becomes (c + id) = ac + iad. For example, we multiply 2 with 1 + 3i as: 2× (1 + 3i) = 2 + 6i Then, if we do multiplication of a purely imaginary number of the form bi with a complex number, then the fo...
