Compare y = sin x and y = cos x , name their similarities and differences
-------------------
graph%28400%2C400%2C-6%2C6%2C-1.5%2C1.5%2Csin%28x%29%2Ccos%28x%29%29
-------------------
Same amplitude
Same period
Difference phase shift.

a) similarities
amplitude (height) is 1
period is 2pi (length of one cycle)
frequency is 1 cycle in 2pi radians
domain is all real numbers
range is y is greater than or equal to -1 and less than or equal to 1
b) differences
sin x has 0 as y intercept
cos x has 1 as y intercept
sin x has 0, pi and 2pi as x intercepts
cos x has pi/2 and 3pi/2 as x intercepts
