comment If the letters T*(RBJBR)=VPLNT each represented a unique digit, and “RBJBR” was a five digit number, what are possible values for the letters?
Whoops, now I should go back through my questions and click those marks.

@BrettFrankel I have no idea what that means. New here. :D Apologies about the tag misplacement, I'm not sure where I should put it.

@SivaramAmbikasaran I'm new to LaTeX. Give me a bit of leniency. :P

@RagibZaman Oh, I get it! Thanks.

Where did the 2 coefficient right after the S come from?

The section of the text it's in suggests definitive evaluation methods. Which is what gets me, otherwise I could just apply Simpson's.

comment Convergence/Divergence of infinite series $\sum_{n=1}^{\infty} \frac{(\sin(n)+2)^n}{n3^n}$
I'm sorry--I just got past introductory proof based mathematics and into abstract algebra, so I'm having a bit of difficulty following this answer. We've not dealt with modulo multiplication groups yet, so I'm not sure what just happened at the beginning of this solution.

The probabilistic argument is that the series converges, but interestingly enough Mathematica tells me that it diverges. Not entirely relevant, but thought you might be interested.
