Here, F(x, y, c) = x2 + y1 — ex. Implicitly differentiating the given equation with respect to x, we obtain 68 APPLICATIONS OF FIRST-ORDER DIFFERENTIAL EQUATIONS [CHAR 7 Fig. 7-8 Eliminating c between this equation and x2 + y1 — ex = 0, we find Here/(X y) = (y2 - x2)/2xy, so (7.15) becomes This equation is homogeneous, and its solution (see Problem 4.14) gives the …
Differential equations are absolutely fundamental to modern science and engineering. Almost all of the known laws of physics and chemistry are actually differential equations , and differential equation models are used extensively in biology to study
Only the simplest differential equations admit solutions given by explicit formulas; however, some properties of solutions of a given differential equation may ...
