Hi all, i hope some on can help with this ive got no idea were to start!
The formula calculates the the value of 2 components for an electrical system but their values must satisfy both equations.

Frequency = 1 / (2*pi*r*c*sqrt6)

Angle = arctan (Xc / R)

Were Xc = 1 / (2*pi*frequency*c

The idea of the formula is that frequency and angle will be user input variables and the spreadsheet will give the value of r and c that fulfills both of these equations

Any ideas gratefull recieved!

Thanks
Harry
