in chapter eight section two we learn about ampitiude, period, and graphing them coordinating plane.
amp(amptitude)is the distance from zero to the highest point in the vertical graph (aka y-axis).
period is how long it takes a function to repeat itself.
the forms for this problems are: y=AsinBx or y=AcosBx
[A]=amp
two (pie) divided B=period
to graph with a period changes
- divde by five points
- divide by B
- sketch the graph
example: y=-4cos 3x
amp is 4 period 2(pie) divided by B is equaled to 2(pie) divided over 3
then you have to divide 0, (pie) divide 2, (pie), three(pie) divided two and two(pie) by three and then sketch your graph.
