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]

Hi Anduin,

Welcome to the forum. What features does the graph y = sin(x) have? How do they compare to the graphs y = 2sin(x) and y = 3sin(x)?

Thank you! I got the answer!

Can someone also help me with this problem?

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);
