Hey guys, Not claiming to be an expert on numerical methods here but I am doing some digital integration using simpson's rule that takes 10 samples a second to provide me with the "approximate" integral for that time period. Right now I am currently taking the magnitude of the value I receive (before integrating it), it is possible that for some of my samples, within the 1 second time period, could be negative. What does this do to the result of simpsons rule? Will it still provide accurate results or is the error greater? Thanks!
