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)

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

Electricity Electricity: The Mysterious Force What exactly is the mysterious force we call electricity? It is simply moving electrons. And what exactly are electrons? They are tiny particles found in atoms. Everything in the universe is made of atoms—every star‚ every tree‚ every animal. The human body is made of atoms. Air and water are‚ too. Atoms are the building blocks of the universe. Atoms are so small that millions of them would fit on the head of a pin. Atoms are made of even smaller
