Install NDSolve To solve the differential equation, we need to know the solution of the heat equation. One way is to find a numerical solution using the built-in NDSolve[]. Another way is to create the solution by using the NDSolveValue[] or NDSolveValue[] and the derivatives of the solution. Note that NDSolve does not accept the time interval as the result of the differential equation. Therefore, we need to solve it first and then extract the time interval from the solution. “NDSolve”, “NDSolveValue”, “NDSolveValue” are functions which gives the solution of the differential equations. The differential equations are also usually given in the form of ODE. Solving the heat equation NDSolve[{u”[t] – k*u[t] == 0, u[0] == 1, u'[0] == 0}, u[t], {t, 0, 1}] NDSolveValue[{u”[t] – k*u[t] == 0, u[0] == 1, u'[0] == 0}, u[t], {t, 0, 1}] Extracting the time interval from the solution u[t_] = NDSolveValue[{u”[t] – k*u[t] == 0, u[0] == 1, u'[0] == 0}, u[t], {t, 0, 1}]; t0 = u[1]; u[t_] = NDSolveValue[{u”[t] – k*u[t] == 0, u[0] == 1, u'[0] == 0}, u[t], {t, 1, 1 + t0}]; Abstract Background: Pauperism is defined as the state of being poor or indigent. It is one of the indicators for determining the need of social support. Previous studies have identified child pauperism, which is a new concept defined by the International Classification of Functioning, Disability and Health (ICF) definition of pauperism
