Please help me some one I have tried everything to solve the following problem:
Construct a table of Left and Right hand Sums with 2, 10, 50, and 250 subdivisions for cos x
From 0 to Pi/2....
I need numerical approximations for this. I have Tried NSum but either I can't tell it how to take the proper subdivisions or I am worse than I previousley thought in terms of working with this program.
