The same shape as sin(x) but the amplitude is 6 times bigger.
sin(x) max=±1 whilst 6sin(x)max=±6

If y= something then 6×something is also going to make y 6 times bigger.

The curve repeats every 3600 which is 2π radians.
The measure of its repeat is called its pitch. Notice that it crosses the origin. The cos curve is the same shape and amplitude but it is shifted "transposed" to the right by 900 which is π2 radians. The curve crosses the x-axis every 1800 or π2 radians. This is 1/2 the pitch.
