Hello,
On the internet there are a lot of good websites with math resources.
Why make a new one?
Here are a couple of examples:

Hello,
The yellow wire can have several functions depending on the fan type number.
There are fans that show pulses on the yellow wire from a tach sensor.
There are fans that need a pwm signal on the yellow wire to control the speed of the fan.
There are fans that use the yellow wire as an...
Hello,
As tollerances of electrolitic capacitors can be quite large, you could take 16 uF capacitors for all three the capacitors.
Watch the voltage, as two are 450 volts and one is 50 volts.
