First of all I realize that this question has been asked before and answered before and so I appolgize if I am making any of you feel like you're talking to yourselves. But I am curious and the people here are the smartest people I know and so I want to hear from you guys and gals, an answer for this age old question.(adsbygoogle = window.adsbygoogle || []).push({});

When we have an expression like [tex]\frac{dy}{dt}=y+5[/tex] and we are asked to find a solution to this DE we

treat the numerator and denominator as if they were normal functions. How am I to think of this? I mean at a certain values of y and t [tex]\frac{dy}{dt}[/tex] is infact a number.

Oh, bother..... I don't know how to ask the question correctly. What is this dy/dt thing? A change in y over a change in t or a quotent of funcitons or what?

Any help is appreciated very much. I have no problem working the problems from the text but eventually I will need to really understand what is going on so perhaps this is a good place to start.

thanks
