Answer to Question #25182 in Trigonometry for Alec Barger

Question

Bunches of harmonic motion
Graph (on some electronic gadget - not here) a*cos(nx) where you choose the
value of “a” to simply magnify the amplitude enough to see some detail.
If you must; on the TI-84Plus:
Set the angle mode to radians,
Set “window”: x-min=0, x-max=14, x-scl=1, y-min=-5, y-max=5, yscl=
1.
Set up 10 functions using “y=”. Use n = 1, 2, 3, …, 10.
Graph all at once.
If you can arrange to graph it on another device with better resolution, use a
larger n.
Describe the pattern you see. Why does it look that way?
