Question 1010922: Avionne is having trouble with telling the similarities and differences between graphing sine and cosine functions. Explain to Avionne, in your own words, how to graph y = 3 sin 2x and y = 3 cos 2x. Be sure to explain the similarities and differences between the steps for graphing them.

Any cosine or sine will vary between +1 and -1
These 2 functions multiply the sine and cosine by ,
so they will vary between +3 and -3
-------------------------------
If I say , then I have:
and

varies between and ,
so

will vary between and
for each cycle
---------------
Also, the cosine is symmetrical about the y-axis
and the sine is not symmetrical
