Integral of 1/2^n ... got that no problem.

I took AB Calculus in high school, three semesters of calculus in college, and a bunch of calculus heavy linear algebra. I’m certain that I knew how to integrate that thing at some point... it’s pretty sad that now I can only stare at it blankly and at best lean heavily on Wikipedia to find an answer.

What I wrote is an infinite series and it’s much simpler to solve than the integral:

Ha, yup, citing a Wikipedia article too. At least I’m not alone.
