If you`re working in degrees, it`s just the sine curve outset by 90. [img]smile.gif[/img]
So for a single revolution, if sin(0)=0, 180, 360
Then, cos(90) = 0, 180, 360
If cos(0)= 90, 270
Then sin (90)= 90, 270
If you know one, you know the other- the sine of an angle is equal to the cosine of a complimentary angle. [img]smile.gif[/img]
