Crank 1 turns about fixed axis A and ends in round roller a which slides in slot b-b of link 2, the diameter of the roller being equal to the width of the slot. The mechanism is intended for generating sine and cosine functions. Linear displacement x of link 2 is proportional to the sine of angle α of revolution of crank 1, i.e. x=A͞͞B*sin(α)=A͞͞B*cos((π/2)-α).
