It includes:

a/b = c/d (solve ratios)

1/Z = 1/x1 1/x2 ... (parallel resistors, series capacitors)

RSS = sqrt (x1*x1 x2*x2 ...) (root-sum-square)

RMS = sqrt [(x1*x1 x2*x2 ...)/n] (root-mean-square)

max, min, median, mean and standard deviation

conversions between fractional degrees and degree:minutes:seconds

I'll welcome any suitable additions to this tool.
