Trig Graph Transformations

Play with the parameter a. What is the effect of making a bigger?

Hit Reset. Make a = -1. Which below describes the change?

Graph is stretched horizontally. Graph is reflected about the x axis. Graph is stretched vertically.

Hit Reset. Play with the parameter "c". Adjust "c" so that f(x) = sin(x - 90). Which if the following is true.

The graph shifts left 90 The graph shifts right 90

Hit Reset. Now play with the parameter "d" so that f(x) = sin (x) + 2. Which is true?

The graph shifts left 2 periods The graph shifts down 2 The graph shifts up 2 The graph shifts right 2 periods

Hit Reset. What is the period of the sine function?

720 degrees 270 degrees 180 degrees 360 degrees

Let b = 2. What is the period T?

180 720 540 360

Let b = 3. What is the period T?

270 60 120 360

Looking at your results from the last two question, which is the correct formula for the period?

Hit reset. Let b = -1 so that f(x) = sin(-x). Which below describes the change?

The graph is stretched horizontally. The graph is stretched vertically. The graph is reflected about the y axis.

HIT RESET to start. Then follow the directions below.
