William submitted a Comment to Problem 46084. Parabolic Partial Differential Equations: Explicit Method

I think this problem has an error. delta-x = 0.01 m in the first test case, but delta-x = 0.02 m in the second.

William submitted a Comment to Problem 46047. Identify Wagstaff primes

I think the answer to problem 7 should be [0 1 1 1 1 1 1 1 1 0 1 0], because q=31 leads to a Wagstaff prime.
