Hi
what does "Then " means?
What is ?
I decided to use the mean value theorem.Suppose is twwice differentiable and . Prove that with
Hint: consider the function given by
.
Let and .
Then .
(this is done so that ).
MVT gives: using the interval .
I have no idea why this helps me (if it does!).
I have a "comments on the test" sheet where one of my lecturers has written:
I'm going to ask my supervisor on Tuesday why and exactly what complications arise if you do. I expected that when I applied MVT to some reason would reveal itself. Unfortunately this hasn't happened!"..and in the problem apply MVT to on the interval which gives a which could turn out to be 0. The latter can lead to complications and it is easier to use the interval ".
