Are there well known simple operationnal amplifier circuits designs to make purely analog squaring amplifier (for experimental analog computing)?

In order to make analog calculation (for analog regulator simulation), what would be the means to make an squaring amplifier ? There is an obvious solution with a multiplier circuit as pointed here; ...

Do analog circuits exist that are essentially mathematical functions in DC?

I am curious if a class of analog circuits exist that would take say a 0-5 V input signal and output a mathematical function like a sine function mapping 0-5 V to 0-2pi, or a log, exponent, polynomial?...

Multisim, Simulation Error

As the picture describes, the Vout is the division's result, but we have an error. Because my experience with MultiSim is not at a high level, why does this happen? Is this my fault ? ]1

Is there a way of dividing 2 DC voltages? ie Vout = V1/V2

I need to take the ratio of two filter outputs as part of a project. I converted them to DC voltage values using a rectifier and a smoothing capacitor thinking that this would make division easier. ...
