Lesson 8-2: Transforming Trig Graphs


Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Objective:

The student will be able to graph the parent graphs of all 6 trig functions.

  1. Drag the sliders to change the values of a, b, c and d in the function. See how each number effects the graph. Which values of a, b and c make the parent function, y = sin(x)?
  2. Notice that a and b are multipliers or coefficients. What happens when they are zero? Positive vs. negative? Large vs. small?
  3. Notice that c and d are constants, added to or subtracted from the function. What happens when they are zero? Positive vs. negative? Large vs. small?
