Is it not sufficient to note that r^a/(r+1)^a is a null sequence, so anything it is multiplied by will also be a null sequence? (null x bounded = null...etc).
Hi all, my first post so go easy on me! Doing some revision and have been tripped up on a really simple question!
Where f(x) = xCos(x)
Show the bound f '(x)<=6 is valid for 0<= x<=5
I suspect this is an easy solution using the intermediate value theorem!
Thanks in advance,
slippers
