APPLICATIONS OF SECOND-ORDER DIFFERENTIAL EQUATIONS Second-order linear differential equations have a variety of applications in science and engineering. In this section we explore two of them: the vibration of springs and electric circuits. VIBRATING SPRINGS We consider the motion of an object with mass at the end of a spring that is either ver-

We can solve this differential equation using separation of variables. We get Z Z dT T = −k dt, T − Te T0 so T = Te + Ce -kt ln ...

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

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 …

Using (7.2) with Tm = 100 (the surrounding medium is the outside air), we have fCHAP. 7] APPLICATIONS OF FIRST-ORDER DIFFERENTIAL EQUATIONS 59 This differential equation is linear. Its solution is given in Problem 6.15 as Since T = 50 when t = 0,ii follows from (1) that 50 = ce~* (0) + 100, or c = -50.
