Webb7 apr. 2013 · Methods: Simpson’s method of discs-derived EDV and ESV were measured using oﬄine analysis by 1 observer, in both the right parasternal and the left apical views. Measurements were compared between both views and between male and female dogs using a t-test. Reference intervals were established using the mean + 2 9 SD. WebbSimpson’s Rule Formula: Let us suppose we are given the definite integral as follows: \int\limits_a^b {f\left ( x \right)dx} Now, if we want to get the suitable approach of the above integral, we need to make partition of the interval [a, b] into subintervals of even numbers n.
