Maybe or maybe doing something else such as generating a radar PPI
display.

If you have sinus issues, try an antihistamine; no idea what to do
for a cosinus issue.

I remember the mid 60's when I was introduced to the Nike-Hercules
fire control computer that solved the differential intercept equations
in real time.

It had 78 tube based op amps and used motor driven zero set switches,
AKA chopper stabilizers, to eliminate drift.
