There are various reasons as of why such approximations can be useful.
In particular, if fis a monotonic continuous function, then we can write the integral of its inverse in terms of the integral of the original function f, which we denote. Many problems in applied mathematics involve the integration of functions given by complicated formulae, and practi tioners consult a table of integrals in order to complete the integration. However, integration is critical to successfully learning di erential equations. Another integration technique to consider in evaluating indefinite integrals that do not fit the basic formulas is integration by parts.
