Making a shift of sin/cos curve

See how the cos wave seems to move to the left. If you focus on each dot, they are simply moving up and down. Each dot is repeating movement of another on its right, but remaining on the same horizontal position. That's how the over all pattern seems to move in the opposite direction.
