Hi.
I'm trying to determine whether the following ratio
r = (b-a) Integral[ f(x)^2 dx, {x, a, b} ] /
Integral[ f(x) dx, {x, a, b} ]
is always greater than or equal to one for 0 < f(x) <= 1. All values
all real.
I've obtained r>=1 for all tested choices of f(x), but seek guidance to
find the general answer.
Yours truly,
Ronnen Levinson.
P.S. E-mailed CC:s of posted replies appreciated.
