hi all :-) http://www.uploadfileyou.com/files/lwjl1z1nhlwg678w6bvy.jpg [Broken] And now translated (poorly): It is required to develop an integration method to calculate (1) so that (1) would be accurate for every even polynomialfrom the order of 4n+1 and down. A. explain how to choose integraion junctions Xi (i=1->n) and the coefficients Bi (i=0->n). B. calculate Xi, Bi for n=1 C. write the error expression E D. using (1) with the results for case B calculate the given integral (as shown) E. calculte the actual error I'm having trouble in the beginning, I cant seem to understand whats going on even though I solved other problems in this topic. can anyone help me? i think once I solve cases A and B ill figure out the rest by myself :) thanks!
