have the same curve only shifted along the x-axis have an amplitude (half the distance between the maximum and minimum values) of 1 have a period (size of one wave) of 360˚ ...

What do you think the graph of \(y = \cos 2x^\circ\) would look like? amplitude = 1, so the distance between the maximum and minimum values is 2 number of waves = 2 (period is 360˚ ÷ 2 = 180 ...

Unlike the JavaScript version of the CSS trigonometric functions, the CSS functions accept both angles and radians for the argument. Perhaps the nicest thing about having this functionality in CSS ...
