Differential Equations are of the following types. hb``` This function is a modified exponential model so that you have rapid initial growth (as in a normal exponential function), but then a growth slowdown with time. Here "resource-rich" means, for example, that there is plenty of food, as well as space for, some examles and problerms for application of numerical methods in civil engineering. Every home has wall clocks that continuously display the time. Also, in medical terms, they are used to check the growth of diseases in graphical representation. Firstly, l say that I would like to thank you. A differential equation states how a rate of change (a differential) in one variable is related to other variables. di erential equations can often be proved to characterize the conditional expected values. Differential equations can be used to describe the rate of decay of radioactive isotopes.

Mathematics has grown increasingly lengthy hands in every core aspect. Newtons law of cooling and heating, states that the rate of change of the temperature in the body, \(\frac{{dT}}{{dt}}\),is proportional to the temperature difference between the body and its medium. Students must translate an issue from a real-world situation into a mathematical model, solve that model, and then apply the solutions to the original problem. (i)\)At \(t = 0,\,N = {N_0}\)Hence, it follows from \((i)\)that \(N = c{e^{k0}}\)\( \Rightarrow {N_0} = c{e^{k0}}\)\(\therefore \,{N_0} = c\)Thus, \(N = {N_0}{e^{kt}}\,(ii)\)At \(t = 2,\,N = 2{N_0}\)[After two years the population has doubled]Substituting these values into \((ii)\),We have \(2{N_0} = {N_0}{e^{kt}}\)from which \(k = \frac{1}{2}\ln 2\)Substituting these values into \((i)\)gives\(N = {N_0}{e^{\frac{t}{2}(\ln 2)}}\,.
