Modeling is an appropriate procedure of writing a differential equation in order to explain a physical process. Pair of Linear Equations in Two Variables, Meaning, Nature and Significance of Business Finance, Vedantu Many people make use of linear equations in their daily life, even if they do the calculations in their brain without making a line graph. At 11:30 a.m. (corresponding to a time lapse of T hours from the origin), the body temperature is 94.6 F, and at 12:30 a.m. (a time lapse of T +1 hours from the origin), the body temperature is 93.4 F. With this data we obtain, 94.6−70 = eTκ(98.6−70), and so eTκ= 24.6/28.6. They've worked hard, and I'd like to reward them with some economic applications of ODEs, but they can only handle simple separable equations.
