In other words, all coefficients are functions of independent variables.

y = x5 + 37x, x = 1, dx = 0.01. dy/dx + y = ex. Table of contents: Definition; Solution; Solving First Order Differential Equation; Examples Treating dydx like a fraction is, as you have correctly stated, not really correct. What's really going on is the following (to stay with your example): take the d y dx.

d2y = diff(dy ). d3y = diff(d2y ). d3y = -dy. fn(t)=d3y(t). y0=0.

But this implies that ∂φ/∂x= 0. Consequently, φ(x,y)is a function of y only.
