Exercise 18: Find the
sinusoid that matches y = f(x).
Please be patient! On some machines
the graph may take a short time to appear.
On the left is a graph of
y = f(x).
Below the graph you will find three sliders. These sliders will control the values of the coefficients
a, b, and
c in the sinusoid
y = a*cos(b*x) + c.
Move the sliders to make the red graph match the green
graph. Then record the equation of the f(x).
Note: the values of
a, b, and
c should be recorded as whole number multiples of +1/4 or -1/4.
