A first order differential equation connects a function y.t/ to its derivative dy=dt. That rate of change in y is decided by y itself (and possibly also by the time t). Here are four examples. Example 1 is the most important differential equation of all. 1/ dy dt Dy 2/ dy dt Dy 3/ dy dt D2ty 4/ dy dt Dy2
Solutions of the linear differential equation of the type − dy/dx + py = q : A differential equation is called linear if there are no multiplications among dependent variables and their derivatives. In other words, all coefficients are functions of independent variables.

Consider the differential equation () ()1cos .2 dy yx dx =− π (a) On the axes provided, sketch a slope field for the given differential equation at the nine points indicated. (Note: Use the axes provided in the exam booklet.) (b) There is a horizontal line with equation yc= that satisfies this differential
Proof We rewrite the differential equation in the form M(x,y)+N(x,y) dy dx = 0. Since the differential equation is exact, there exists a potential function φ (see (1.9.4)) such that ∂φ ∂x + ∂φ ∂y dy dx = 0. But this implies that ∂φ/∂x= 0. Consequently, φ(x,y)is a function of y only. By a
You may have something like "dy= f(x) dx" but that is just a different way of writing "dy/dx= f(x)". $\endgroup$ – user247327 Dec 25 '17 at 0:28 7 $\begingroup$ The meaning of $\mathrm dx$ in isolation (which can happen, contrary to @user247327's comment) depends highly on the context.
