: : coefficient being positive or negative?
: : y0=-Sqrt(Pi)/2

: That works for me! In theory, how would a "mathematician" do this differently than the physicist approach which you used to solve it?
: Is there a more "formal" way???
Mathematician:
Would formally work out the limit of your function, as t-> infinity.
Physicist:
Just plugged in the "values" at infinity and drop small
terms. Then get on with the physics of the problem.
