These devices included a model " differential analyser, " and the Mallock machine, described as " an electrical simultaneous equation solver . " According to Croarken, the Ministry was also interested in the new arrival of a differential analyzer accommodating eight integrators.

:I believe the great mechanical analog computers of the early-to mid-twentieth century ( in particular various differential analysers ) had both integrators and differentiators, so presumably the answer is yes . talk ) 01 : 39, 7 January 2008 ( UTC)

An example is the differential analyser built at Marshall University, which is now used for educational purposes, in that a student not only solves a differential equation but also becomes the " calculator " by operating the machine, and so develops a better understanding of what a differential equation is.

He was joined by engineers from several companies, along with " Freddie " Williams, who quickly applied some of the techniques he had used on a differential analyser to produce a system known as the Velodyne that tracked smoothly in spite of hard manoeuvring and large crossing speeds by the target.

After 2 or 3 months, Kay and Fran were moved to work on the differential analyser in the basement of the Moore School, the largest and most sophisticated analogue mechanical calculator of the time, of which there were only 3 in the United States and 5 or 6 in the world ( all of the others were in Great Britain ).
