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 stretched vertically. Graph is reflected about the x axis.

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. [br][br]Which is true?

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

Hit Reset.[br][br]What is the period of the sine function?

360 degrees 720 degrees 270 degrees 180 degrees

Let b = 2. What is the period T?

180 720 360 540

Let b = 3. What is the period T?

120 360 60 270

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

[math]T=\frac{b}{360}[/math] [math]T=360b[/math] [math]T=\frac{180}{b}[/math] [math]T=\frac{360}{b}[/math]

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

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

HIT RESET to start. Then follow the directions below.
