Actuary in the making
Hey there, its been awhile since i've done my maths
and now i'm doing actuary!!
so i am rusty... and am wondering (from u genious's) how do complete these so called simple calculus questions...
1. Deduce that a+b/2 >= root(ab) for all non0negative real numbers, a,b. When does the equality hold?
i did the deduction, now i dun understand the second part... cheers
2. Show graphically, or otherwise, that
sinx = mx
has no non-zero solution for -pi < x < pi when m<0
thanks
