Complex Numbers 1 Introduction
... A complex number is defined by it’s two real numbers. If we have z = a + bi, then: Definition: The real part of a + bi is a, Re(z) = Re(a + bi) = a The imaginary part of a + bi is b, Im(z) = Im(a + bi) = b To visualize a complex number, we can plot it on the plane. The horizontal axis is for the rea ...

31-intro to sequences
... A sequence is an ordered list of elements. It is a function whose set of inputs are x -values. A sequence is often shown as an ordered list of numbers, called the terms or elements of the sequence. Terms in a sequence are typically indexed by a subscript starting at 1. Example 1: Consider the seque ...
