TI-89 Titanium graphing problem
Hi all, found this forum while looking for a solution to this problem:

When I graph a y1=sin(x) I get the sin wave you would expect.


When I graph y2=5+4*sin(pi/12)(x+10) I get a line instead of a wave?

What gives? I'm in radian, I reset my factory defaults... Am I entering this wrong? Shouldn't that give you a sin wave?

Thanks for your help!

You have to pan left to about x=-15 to see it

Well, fooplot gave me the same thing, so why am I expecting this to be a sin wave?
