Ok so i have a function(adsbygoogle = window.adsbygoogle || []).push({});

cos4/3x between 0<= X <= 2π

the amp is 1, max is 1 and min is -1.

the period is 3π/2.

normally in a cos graph, π/2=0, π=-1, 3π/2=0 and 2π=1.

but since the period is 3π/2, i know the 1 is now at 3π/2. But Im getting confused as to where the 0s and the negative -1 would be at.
