mathematically calculate how an AC circuit is designed to operate and locate problems in the

circuit. You will use simple trigonometric functions, the Pythagorean theorem, and work with

coordinates, axes, and vectors.

You will solve for an unknown side of a right triangle using trigonometric

functions and Pythagorean theorem, determine the angles of right triangle

using trigonometric functions, plot a sine wave, determine the magnitude

of the x and y-vectors for a given angle, and relate coordinate notation and

vectors to sine waves.

Given trigonometric tables and appropriate information about the lengths

of sides of triangles, magnitude of vectors, and angles of vectors.

All calculations are performed correctly to one decimal place.

A.C. circuits work differently than D.C. circuits. You will learn how to calculate and

monitor the operation of a circuit. In troubleshooting an electronic piece of equipment, you

need a good understanding of what is supposed to happen, and what is actually happening.

By mathematical calculations, you will figure what is supposed to happen, and by using test

equipment, you can determine what is actually happening.
