if some explanation could be given, that would be great. Text just throws these terms out there while dealing with trig functions, but doesn't explain what or how to locate them.

State the period and amplitude for the following equations:
y = 4sin(2x)
y = 3cosx
y=cos(2x)

for any eq y = asin(bx) then a is the amplitude and the period is 2pi/b

y = 4sin(2x) amp = 4 period = 2pi/2 = pi
y = 3 cosx amp = 3 p = 2pi
y = cos(2x) amp = 1 p= pi
