..im really stuck on this. can someone please explain?

Figure A [[which i tried to recreate below]] is a partial graph of the position function x(t) for a simple harmonic oscillator with an angular frequency of 1.1 rad/s.

What is the phase constant of the SHM if the position function x(t) is given the form x = xmcos(ωt + φ)?
φ = ____ rad/s
..... the example in the book had an angular frequency of 1.2 rad/s. & the answer it gave was 1.03 rad/s.
sorry that the 'graphs' look distorted on this page that your viewing... i recommend copying the graph and pasting it in the ANSWER box below on this page and it should look right :)
