When you are trying to find an integral and you are dealing with two curves, and the formula calls for [itex] f(x) [/itex], I know that you do [itex] f(x) - g(x) [/tex] and put in that value for the f(x) in the original formula.(adsbygoogle = window.adsbygoogle || []).push({});

When the formula calls for [itex] f^2 (x) [/itex], do you do [itex] (f^2 (x) - g^2 (x)) [/itex] or [itex] (f(x)-g(x))^2 [/itex]
