Let me explain this by way of an analogy. Suppose I teach you all the rules for adding and multiplying rational numbers. Then you ask me "But what are the rational numbers?" The answer is: They are anything that obeys those rules. Now in order for that to make sense, we have to know that there's at least ...Fri, 03 Apr 2026 12:25:00 GMThttps://math.stackexchange.com/questions/23902/what-is-the-practical-difference-between-a-differential-and-a-derivativeSee this answer in Quora: What is the difference between derivative and differential?. In simple words, the rate of change of function is called as a derivative and differential is the actual change of function. We can also define a derivative in terms of differentials as the ratio of differentials of function by the differential of a variable.Sat, 04 Apr 2026 15:37:00 GMThttps://math.stackexchange.com/questions/3379173/what-actually-is-a-differentialI am a bit confused about differentials, and this is probably partly due to what I find to be a rather confusing teaching approach.

But order of a differential equation is always defined.Sun, 29 Mar 2026 15:23:00 GMThttps://math.stackexchange.com/questions/128543/how-to-derive-a-differential-equation-of-an-ellipseI am quite new to differential equations and derivatives.

I mean we are defining differential by differential itself. Can we define differential more precisely and rigorously? P.S. Is it possible to define differential simply as the limit of a difference as the difference approaches zero?: $$\mathrm {d}x= \lim_ {\Delta x \to 0}\Delta x$$ Thank you in advance.Sun, 29 Mar 2026 12:53:00 GMThttps://math.stackexchange.com/questions/3650360/why-are-certain-pde-called-elliptic-hyperbolic-or-parabolicWhy are the Partial Differential Equations so named? i.e, elliptical, hyperbolic, and parabolic.
