Determine the frequency of y = 2 - 3 cos 10x. (nearest tenth)

frequency is applied to a trig function which is dependent on time, not position.
If you had y=2-3cos10t, then frequency would be found by 2PI*frequency=10
and f= 1.59rad/sec
I am wondering if your teacher is using a private definition of frequency.
