Complex Numbers and Applications ME50 ADVANCED ENGINEERING MATHEMATICS 1 Complex Numbers √ A complex number is an ordered pair (x‚ y) of real numbers x and y. For example‚ (−2.1‚ 3.5)‚ (π‚ 2)‚ (0‚ 0) are complex numbers. Let z = (x‚ y) be a complex number. The real part of z‚ denoted by Re z‚ is the real number x. The imaginary part of z‚ denoted by Im z‚ is the real number y. Re z = x Im z = y Two complex numbers z1 = (a1‚ b1) and z2 = (a2‚ b2) are equal‚ written z1 = z2 or (a1‚ b1) = (a2‚ b2)

HISTORY OF MATHEMATICS The history of mathematics is nearly as old as humanity itself. Since antiquity‚ mathematics has been fundamental to advances in science‚ engineering‚ and philosophy. It has evolved from simple counting‚ measurement and calculation‚ and the systematic study of the shapes and motions of physical objects‚ through the application of abstraction‚ imagination and logic‚ to the broad‚ complex and often abstract discipline we know today. From the notched bones of early man

The evolution of mathematics might be seen as an ever-increasing series of abstractions‚ or alternatively an expansion of subject matter. The first abstraction‚ which is shared by many animals‚[19] was probably that of numbers: the realization that a collection of two apples and a collection of two oranges (for example) have something in common‚ namely quantity of their members.Evidenced by tallies found on bone‚ in addition to recognizing how to count physical objects‚ prehistoric peoples may have

Most people are not familiar with the concepts of mathematics and mathematizing. Once they hear any of these terms‚ they connect them to education. The next discussion will attempt to shed some light on these two concepts by defining mathematics as a language. First‚ it will define these two terms with examples. It will then point out various differences between mathematics and mathematizing while giving examples. Finally‚ it will elaborate the importance of both concepts to humans and how they have

mathematician that lived in Alexandria in the 3rd Century. His estimated birth and passing years are said to be from 150 B.C. to 350 A.D. Although there is not enough information about his life‚ there is a riddle that estimates how long he lived. The mathematic puzzle is known as ‘Diophantus Riddle’. The riddle states he married while he was 33‚ then he had a son who lived for 42 years and the total years Diophantus lived according to the riddle was a total of 84 years.

Summarize the concepts that you used in the lab (1-2 paragraphs). For lab 11‚ I used the concept – Stellar Evolution. It is the process of showing a star changes over the course of the time. Also‚ it relates to the mass‚ ages‚ sizes of the stars. Also‚ I used the Hertzsprung-Russell (H-R) diagram concept to classify the stars and find the Main Sequence. When the stars are hotter and more luminous‚ they main sequence tends to follow a band going from the bottom right to the top left at the diagram
