It is not your answer but the series itself.

When x = 1 + (1 /4 ) it is not true. Also for other values too. That does not mean there is something wrong with it as you say. It just means I am not able to verify it.

For a sum of 10000 terms;
x=N[1+1/4,20];
FullSimplify[Sum[(-1)^k Binomial[2k,k]*(Cos[2k+1]x)/2^(2k),{k,0,10000}]-Cos[x/2]/Sqrt[2Cos[x]]]//N
Answer should be getting close to 0, but it does not. When I do 20000 the answer goes up instead of down!

As you approach infinity it should be going to 0. But it does not.

Hi;
Could just be round off error. I got it to work for one value so just submit it to gAr and see if he likes it.
I am going to go shopping see you later.

Sometimes! The ones that you solve in a day or two are fun. But there are those that last for years. Nothing you try works, I have a number of those.
Could you tell me one of them,bobbym?

This is the easiest one:
Evaluate the above integral to as many digits as you can. Find a good way to do so.

Everything I know of course and a few more things. I bounced it around on forums and got a lot of punk answers. Two people did show me something, one was a certain Robert MIller, the other I do not remember. Currently even with a computer and the big boy on the block, I can get only around 100 digits or so easily.

Many others but most of them I cannot recall offhand any longer. I outlined 6 or 7 for gAr when we were talking about this. Oh, here is another:

There are several approaches to get the front digit.
Where do I get the problems from? You are familiar with Christian Goldbach?
