Lately, I have been trying really hard to understand the Newton Leibnitz Formula for evaluating Definite Integrals. It states that-(adsbygoogle = window.adsbygoogle || []).push({});

If f(x) is continuous in [a,b] then [itex] \int_a^b f(x) dx = F(b) - F(a)[/itex].

But one thing that just doesn't make sense to me is that why should f(x) be continuous in [a,b] if we need to apply this formula?
