The solutions here are numbers or a set of values or set of values that satisfy the equation. Here it's a relationship between a function and its derivatives and so the solutions or the solution is going to be a function or a set of functions. Now let's make that a little bit more tangible. What would a solution to something like any of these three which really represent the same thing, what would a solution actually look like? And actually let me move over to the, let me move this over a little bit. Move this a little bit so that we can take a look at what some of these solutions could look like. Let me erase this little stuff that I have right over here.
