In this chapter, first order linear differential equations together with the
nonlinear Bernoulli equations are considered and methods for obtaining their solutions
discussed. The methods are applied to find solutions to models in the vibration of LR
electrical circuits, radioactive dating, population dynamics, chemical reactions,
epidemiological and pollution problems.
Keywords: Chemical reactions, Epidemiological, Population dynamics, Pollution problems, Radioactive dating, Vibration of LR electrical circuits
