Answer 1

\[(-1/2)e^{1/x^2}\]

Answer 2

can you explain the steps

Answer 3

Sorry. The computer program I use doesn't show the solution steps. There was a two volume series titled, The Differential Equations Problem Solver, Vol 1 and Vol 2, by the Research and Education Association available used at one time. I am holding Vol 1: ISBN 0-87891-513-3 They claimed that they had solved about any problem class that would be presented in an academic test.

I am 67 years old and if I were attempt to solve some of the problems on this site with pencil and paper then I would probably be running out into the street with my hair on fire.
