I was wondering. Say I'm given th diffrential euqation y' = f(x,y). Is there any way I can draw, at least approximately, the graph of the solution y(x), without solving the equation?
Thanks for the response.
I figured as much, but I'm having a hard time drawing a slope field for
y'=x^2 * siny.
That's a strange thing. This excercise is under the title " the Uniqueness and Existence sentence", but what they ask me to do is to sketch the solutions (notice the 's' in solutions) of the problem. As far as I understand, this problem has only one solution, given a side condition (y(x0)=y0), and it is defined on all of R.
Should I just draw the solution's graph or what?
