Abstract : Methods are developed by which programming for obtaining graphical solutions of differential equations on an analog computer can be accomplished (a) with bounded variables only and (b) without the use of division circuits, often required with conventional methods. The important advantages of the techniques are: (1) Simplified scaling and increased accuracy. Also, singularities can be approached without rescaling. (2) A solution of a differential equation can frequently be continued through a singularity without reprogramming. All discussions are elementary. Many examples are given and certain difficulties are discussed. (Author)
