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.
- How do you find the amplitude, period, phase shift, and vertical shift of y = (3/2)cos(2x-3*pi)+5?
- What do the letters or variables stand for and how can you use them to find amplitude, period, phase shift, and vertical shift in y = a*cos(b(x - c)) + d?
This lesson shows how to find the amplitude, period, phase shift, and vertical shift of a trig function. All steps necessary to find these values are explained. Finding these values can be very useful when you need to graph the function.
