Unformatted text preview: answer. (a) The series ∑ ∞ n =1 (-1) n n a is always convergent, no matter what pos-itive real number a is. (b) If in a Frobenius equation, we have q ( x ) = e x /x 2 , then 0 is a regular singular point of that equation. (c) If a function is of exponential order, then its Laplacian exists. 1...
