A four bar linkage can be designed such that its output motion is a function of its input motion. When five pairs of displacement angles are to be included in the design, the starting configuration of the mechanism is completely specified. This means that not only the link sizes are specified but the starting angles of the input and output links are also specified. Previous work in the synthesis of function generators has demonstrated how these starting angles and link sizes can be made compatible with five precision points, which in the physical sense are the five pairs of displacement angles. The previous work is extended to include precision first and second derivatives in the design calculation.
