A patient receives an injection of a drug at regular intervals with period T. In between injections, the concentration c(t) of drug exhibits exponential decay in the body with coefficient a. That is, there is a mixture of a discrete process (injections) and a continuous process (the decay).Let c, denote the concentration in the blood stream immediately after the nth injection. a) Set up and solve a difference equation for cn

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
