Estimate the following using tzoidal approximation with n=3???

trivial for you to do following the concepts of this type of numerical integration...I ume you have studied the topic and that you know how to find areas of tzoids.....let h =[b-a]/n ....h / 2 * { f(a) + 2 f(a+h) + 2 f(a +2h) + f(b)} in your case.....about 4.65
