You have the formula- just plug in the data for this problem.

The only "hard" part is finding the general derivative.

If

, then

,

,

...

Do you see the pattern? Obviously, there is an alternating + and -:

since this is + for n odd, - for n even.

The denominator of the fraction is a power of 2:

.

The numerator is a little harder- it is a product of odd integers from 2n-1 down: 1*3*5*7... We can write that more compactly by filling in the missing evens:

. And we can write

**that** denominator as

.

The fraction is

and the exponent on x+ 1 is

.

That is,

.

Using that, find a maximum on

between 0 and x.
