thanks, but i'm still unclear on the phase shift because here http://www.mathhelpforum.com/math-he...rig-work2.html in question 2 you stated it is the value of b,the phase shift, and i stated in question 2 here that the phase shift is pi/4?

for 4 it would be 6 units left, right?

and for 1 the period is 2pi/3, right?

thanks

b and are in the same place in there respective equations so they mean the same thing.
