hmm, still don't get it. why is it pi/3 and not pi/4?

is there a different way to solve it.

does this way work?
sin3(x-pi/4) = 0 ?

If you have a domain restriction, for instance solve:

,

Then you just do this:







So for you will want to have values in

Find the domain for which we will solve for x:








Shouldn't it be:

What I mean is, if you found the answer to that question you will have answered it.

You have a function which equates to 0.

So what values of are such that ?

If 2sin(......)=0  then whatever is in the brackets must be equal to zero, pie, 2 pie, 3 pie ect.

e.g. sin(0)=0
      sin(pi)=0
      sin(2pi)=0

Well the next step is really up to you. Just solve for x normally :)
