comment Application of the Poisson distribution - flaws on glass.
That was my mistake - 3 flaws. It appears it would be rare from the calculation. I thought we use Poissoin distributions when we are working with averages.

comment Vibrating string - separation of variables
Is my $\lambda_n$ correct?

I'm referring to what's going on with the coefficient stuck to $D$.

comment Vibrating string - separation of variables
I'd like to know if my coefficients are correct before I commit to, what looks like, nonsense.

I'm pushing through the conditions again. I'm still getting these ugly coefficients - this is why I'm concerned.

comment Separation of variables in the PDE $u_{tt}=c^2 u_{xx}$.
I'm not sure if there is an error in my book or not, but the answer provided is $\sum\limits_{odds}\frac{32[(-1)^n-1}{\pi c n^2(n^2-4)}$

That's where I'm kind of stuck - I'm not sure how to find these coefficients.
