WebThe two integrals are not the same, because the limits of integration are not the same. You mean to say that the integrands of the two integrals are the same. Jan 16, 2014 at 17:52 Well @DavidH : the two integrals aren't the same, true, but not because the integrals' limits are different. Jan 16, 2014 at 17:55 Add a comment 2 Answers Sorted by: 3 WebApr 9, 2015 · Using an integration variable (the x in ∫ d x) that matches one of the limits of integration runs counter to the conventions normally used. It is "bad" in the sense that you may know what you mean by it, but that meaning can get very ambiguous for all but the simplest of expressions.

WebThe integration rules are rules used to integrate different types of functions. We have seen that ∫ 2x dx = x 2 + C as d/dx (x 2) = 2x. This can be obtained by the power rule of integration that says ∫x n dx = x n+1 / (n+1) + C, where 'C' is the integration constant (which we add after the integral of any function). WebLearn.
