Therefore I want to perform the integration with Romberg's method. 1212 [1] (e) Since Simpson's method is a second order method, and the circle is a second order equation, why doesn't Simpson's method give an exact answer? The order of integration (and therefore the bounds) is from the innermost integral to the outermost one. Your feedback and comments may be posted as customer voice. We will use this integral to illustrate how Romberg integration works. Simpson's 1/3 rule, also simply called Simpson's rule, is a method for numerical integration proposed by Thomas Simpson.
