State the amplitude, period, and phase shift of the function.
h(t)=9cos(7tPie/5)
I got the amplitude and the period. For the phase shift I got (Pie/5)/7 but its wrong. Can someone tell me what I did wrong?

h(t)=9cos(7tπ/5)
or
h(t)=9cos 7(tπ/35)
the phase shift is π/35 to the right,
your answer of π/5/7 is actually right, except it is not written in good form. It is ambigious, does it mean
(π/5) / 7 or π/(5/7)
