## Objective:

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

- 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)*?
- Notice that
*a* and *b* are multipliers or coefficients. What happens when they are zero? Positive vs. negative? Large vs. small?
- 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?
