So How Old Are You?

24.9 (I don't know what you want it rounded to)

I'm uncertain about limits approaching infinity, but I'm pretty sure, and it came out reasonable, so I reckon it's right.

You should get an integer. What did you get for your integrals?

Ok, it's not 24.9. It's 20. Very nice expression you have there.

sec^2 integral is easy, giving root3, so +3-1 at the end of the expression.

The other integral comes out as tan^-1(e^x) between r and 0. tan^-1 in this sense is the inverse of tan, not cot.

As x -> infinity, e^x -> infinity. tan^-1(infinity) approaches pi/2.

tan^-1(e^0) is tan^-1(1) which is pi/4.

So pi/2 -pi/4 which is pi/4.

74pi/4pi is just 74/4 which is 18. Adding the two from above gives 20.

Just had to have another look at that first integral.

Ding Ding Ding!!!!!!!!

Correct! Yes I am 20 years old! Nice job!

I'll write my own soon. I have a few ideas.

What program did you use to set it out like that?
 
I'm on a math forum too and you can use the forum code to make the notation. Then I just screen captured the image.
