1. The problem statement, all variables and given/known data Hi guys, my question is from a book on differential equation. It asks me to give a differential equation that has only a trivial solution, y = 0. 2. Relevant equations 3. The attempt at a solution I give it some thought and I can only think of a diff eq'n of y' = y, however, in this case y = e^x will also be a valid solution but not a trivial one. So I am not so sure if this is what the question wants, or there is a diff eq'n that has only one solution which is y =0. Thank you in advance.
