If we assume that the time rate of change of this amount of substance, \(\frac{{dN}}{{dt}}\), is proportional to the amount of substance present, then, \(\frac{{dN}}{{dt}} = kN\), or \(\frac{{dN}}{{dt}} kN = 0\). di erential equations can often be proved to characterize the conditional expected values. \(m{du^2\over{dt^2}}=F(t,v,{du\over{dt}})\). It appears that you have an ad-blocker running. They can get some credit for describing what their intuition tells them should be the solution if they are sure in their model and get an answer that just does not make sense. It involves the derivative of a function or a dependent variable with respect to an independent variable. Similarly, the applications of second-order DE are simple harmonic motion and systems of electrical circuits. The Simple Pendulum - Ximera Overall, differential equations play a vital role in our understanding of the world around us, and they are a powerful tool for predicting and controlling the behavior of complex systems.
