Hi;

Actually,my brother challenged me to solve it,and I couldn't solve it,so I came here for help.

I think you should re-challenge your brother and humbly ask him for the solution.

It is probable nobody has a solution (other than W|A's series).

It looks like something that he made up on the spot and he probably does not have a solution at hand.

Correct, that is one use of a CAS!

I hope I am wrong, it has always been my quick go-to way of checking my answers.

You might be right. Corporate boobs think only in terms of money. They only know two ways to make it. Charge for what is currently free and raise the price on what isn't.

Soon W|A will not be free at all.

I have emailed them several times to not put any restrictions on the site such as that. Seems like every time I did they took something away.

I see.

They also appear to have blocked you from using the 'more time' command, unless you are a subscriber.

Hi;

That is done with the Series command. Mathematica can differentiate anything so Mclaurin series are easy for it.

I wonder how W|A got their series. This certainly does not look very nice. Unless there is some sort of extraordinarily clever substitution that can be made here.

Hi;

Most do not. I am unable to find one for that.

Hi

That function doesn't have an antiderivative among the standard mathematical functions.

Where does that integral come from anyway?

How do I solve this-
