Best ResponseYou've already chosen the best response.0my attempt: \[\int\limits_{3}^{3}\sqrt{9x ^{2}}\approx \int\limits_{3}^{1.5}\sqrt{9x ^{2}}+\int\limits_{1.5}^{0}\sqrt{9x ^{2}}+\int\limits_{0}^{1.5}\sqrt{9x ^{2}}+\int\limits_{1.5}^{3}\sqrt{9x ^{2}}\]

Best ResponseYou've already chosen the best response.0ok...I have forgotten the formulas anyway...so i can't solve it even though i tried....and i really have never seen this way of solution...maybe u in USA r smarter :P:P

Best ResponseYou've already chosen the best response.0following from the top i get \[\int\limits_{3}^{3}\sqrt{9x ^{2}}\approx 3/4(\sqrt{18}+\sqrt{45}/2)+3/4(3+\sqrt{45}/2)+3/4(3+\sqrt{27}/2)+3/4(\sqrt{27}/2+0)\]

Best ResponseYou've already chosen the best response.0the rule in my textbook is \[\int\limits_{a}^{b}f(x)dx \approx( (ba)/2) (f(a)+f(b))\]
