Patent US 4,181,971

Disclosed is a device which can utilize, as an input signal, the solution to mathematical problems from an analog computer or which can be used directly with a process that is governed by a mathematical problem to pictorially depict the solution to the problem. The problem being solved can be dynamically displayed on a device such as a conventional television receiver for use by a student, technician or the like. The input signal indicative of the solution of the mathematical problem is fed to a memory and control device which can store the same for subsequent use. The memory also has stored therein data representative of the images necessary to create the pictorial representation of the problem. A programmable device, preferably in the form of a digital computer, interprets the input signals and directs the data in the memory so that it is properly displayed on the television receiver.
