I thought phase shift was theta over omega correct???
and the period equals two pi over omega
40 min = (2pi)/omega
omgea = pi/20 min
phase shift = theta over omega
phase sift = (20?)/pi min
now you said phase shift was (35 pi)/40
I do not see why
I appologize i made a spelling mistake when wrote shift and acendentally forgot the f and the forums were not to happy :O
