**Reiny**, Monday, March 18, 2013 at 2:04pmyour first equation

y=1/2 cos 3pi/2 has no variable on the right side, so it is simply a straight line y = 0 or the x-axis

for y = 2 cos πx/2

the period = 2π/(π/2)

= π(2/π) = 2

after you find your typo, in the first equation,

take 2π/(coefficient of the angle) to get the period
