why is that. it doesn't seem to me you have trouble with finding derivatives. find the derivative using the quotient rule, then set the numerator equal to zero and solve for p, this will give you the p-values for the critical points.

if you get stuck, come back

Some books (at least) also define p values where the derivative doesn't exist to be critical points as well.

ah yes, that is true, i've seen that somewhere before. i find that weird though. i guess kwivo has to check his text

i like your definition of "philosophy." the definition of "adverse" is nice too
