2. RP Linear Guess
By examining a plot ofsqrt(f)
for 0.5 <= f < 2.0:
we may guess at a pretty good linear approximation which is exact for
f=2, and has a g-axis intercept of 0.5:
g = 0.5 + f*(sqrt(2)-0.5)/2 g = 0.5 + f*0.45710678118654757
sqrt(f)
for 0.5 <= f < 2.0:
f=2, and has a g-axis intercept of 0.5:
g = 0.5 + f*(sqrt(2)-0.5)/2 g = 0.5 + f*0.45710678118654757
