To make a three phase generator you have to place a certain number of magnets on your stator and armature, all with proper spacing. Electromagnetism is as complex as dealing with waves and water, so you need to know how to control the field through your design.
Tutorial 20: Solving Systems of Linear Equations in Three Variables will cover systems that have three equations and three unknowns. We will look at solving them three different ways: graphing, substitution method and elimination method. This will lead us into solving word problems with systems, which will be shown in Tutorial 21: Systems of Linear Equations and Problem Solving.
Page 1 of 2 632 Chapter 10 Quadratic Relations and Conic Sections Solving Quadratic Systems S OLVING A S YSTEM OF E QUATIONSIn Lesson 3.2 you studied two algebraic techniques for solving a system of linear equations. You can use the same techniques (substitution and linearcombination) to solve quadratic systems. Finding Points of Intersection Find the points of intersection of the graphs of x 2 + y 2 = 13 and y = x + 1.S OLUTION To find the points of intersection, substitute x + 1 for y in the equation of the circle.
