The mechanism is intended for generating tangent and cotangent functions. When slotted link 1 is turned through angle α, slider 2 is moved to a position at the distance x which equals x=l*tan(α)=l(1/cot(α)). The mechanism can generate functions of the tangent and cotangent within definite limits of angle a which are restricted by the length of slot a-a of link 1.
