Hi all
I hopw this is the correct forum for this post, but here goes.
I have the following equation :-
$\displaystyle y=a+b*log(x) + c*log(x)^2$
This basically describes the power conversion efficiency from AC Watts input (x) to DC Watts output (y) for a power supply.
I need to reverse the equation so that I can find the AC Watts input (x) from the DC Watts output (y).
This has got me stumped
Cheers
Andy
