Lesson Summary:

In this trigonometry lesson, the teacher guides students through determining the amplitude, period, phase shift, and vertical shift of the function y = (3/2)cos(2x-3*pi)+5. The amplitude is found by identifying the coefficient, the period is calculated by dividing the regular period of cosine by the coefficient of x, and the vertical shift is the value added or subtracted to the function. The phase shift is found by factoring or solving for x, and this lesson provides options for learners having difficulty with either method.

Lesson Description:

State the amplitude, period, phase shift (how many units left or right), and vertical shift (how many units up or down) of y = (3/2)cos(2x-3*pi)+5. Solutions to a Review for a Trigonometry Test for a class. . See pdf on that site under Trig, special videos.
