Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum. The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.
The period is 2*pi which is equal to 6.28. This is because both the sine and cosine functions repeat every 2*pi. The amplitude is 1.41 because that is the farthest distance from the axis that the function ever reaches. It occurs at 45 degrees, or pi/4 if you are dealing in radians. I hope this clears things up a little bit!
