CHAPTER 7 Applications of First-Order Differential Equations GROWTH AND DECAY PROBLEMS Let N(t) denote ihe amount of substance {or population) that is either grow ing or deca\ ing. It' we assume that dN/dt. the lime rale of change of this amount of substance, is proportional to the amount of substance present.

First Order Differential Equations In “real-world,” there are many physical quantities that can be represented by functions involving only one of the four variables e.g., (x, y, z, t) Equations involving highest order derivatives of order one = 1st order differential equations Examples:
