Both have a max at 1 and a min at ­1
Both have a period o
of 2 (or 360 )
y = sin x "starts" at the origin (0,0)
y = cos x "starts" at the max, (0,1)
Title: features (5 of 9)
Key features of the sine and cosine graphs:
y = Asin( x)
y = Acos( x)
A ­ Amplitude (distance from max or min to the center line)
T ­ Period (length for the function to repeat itself)
T = Title: features (6 of 9)
