Hi! This problem has also been giving me trouble. I am looking for either hints or a solution to this problem. Everything is greatly appreciated. Thank you!

Below is the graph of

, where
,
, and
are positive, and
is as small as possible. Find
.

[asy]
import TrigMacros;
size(400);

real g(real x)
{
return -2*sin(2*(x/3 + pi/4))+1;
}

trig_axes(-3*pi,3*pi,-2,4,pi/2,1);
//layer();
rm_trig_labels(-5, 5, 2);
draw(graph(g,-3*pi,3*pi,n=700,join=operator ..));
label("$1$",(0,1),W);
[/asy]

Hello... I am having difficulty trying to solve this problem. I would like an answer to it, but an explanation. Thank you!

Below is the graph of

, for some positive constants
and
. Find
.

[asy]import TrigMacros;
size(400);

real g(real x)
{
return 3*cos(pi/2 - x/2);
}

trig_axes(-3*pi,3*pi,-4,4,pi/2,1);
layer();
rm_trig_labels(-5, 5, 2);
draw(graph(g,-3*pi,3*pi,n=700,join=operator ..));
label("$1$",(0,1),W);
[/asy]
