Compact operational amplifier designed for a table model computer

THE MANY PROBLEMS that are often encountered in the fields of engineering and science are generally approached by the method of expressing the problem by mathematical symbols and equations. By applying mathematical methods that are governed by proved theorems, it is possible to obtain solutions to the majority of these equations without encountering very much difficulty; yet there are many equations, the solution of which require many hours of computation. There are also many equations which cannot be solved by the ordinary or advanced mathematical techniques known today.
