Homework Help: Pre-cal

Posted by Abi on Thursday, June 20, 2013 at 8:25pm.

I'm supposed to graph y= 4+2sin (pi/6 t -pi/5)

i have the vertical shift d=4
amplitude 2
level line y=4
crest line y=6
trough line y=2

but i am not sure what the period is
formula for period 2pi/b
in this case 2pi/pi/6 => 12pi/pi

do the pi's cancel, leaving the period at 12????

am i doing this right?
