Hi Forum

I started reviewing some of my calculus material and I found this unanswered question.

Now, Wolfram tells me to actually calculate

And I don't remember dealing with something like this before.

So, is there an easy way to solve this?

Maybe I just got a sadistic teacher hahahaha

Oh, I don't have any of that handy calculators, I usually do it all by hand.

I really hope something like this doesn't pop up in a test.

Thanks!
