  • What is the integral of 1 x? - Mathematics Stack Exchange
    $\begingroup$ "Answers to the question of the integral of 1x are all based on an implicit assumption that the upper and lower limits of the integral are both positive real numbers" --- not completely correct: if they are both negative it also works This is an improper integral and does not converge in the remaining cases $\endgroup$ –
  • calculus - Is there really no way to integrate $e^{-x^2 . . .
    $\begingroup$ @user599310, I am going to attempt some pseudo math to show it: $$ I^2 = \int e^-x^2 dx \times \int e^-x^2 dx = Area \times Area = Area^2$$ We can replace one x, with a dummy variable, move the dummy copy into the first integral to get a double integral
  • Newest integration Questions - Mathematics Stack Exchange
    For questions about the properties of integrals Use in conjunction with (indefinite-integral), (definite-integral), (improper-integrals) or another tag(s) that describe the type of integral being considered This tag often goes along with the (calculus) tag
  • What is an integral number? - Mathematics Stack Exchange
    In normal use, integral length would be equal to some integer, while unit length would be of length $1$ (see "unit number" here) Presumably the author meant, "in the unit ( with a different meaning! ) we use to measure lengths, these lengths are integer-valued"
  • Integral of an absolute value function - Mathematics Stack Exchange
    The absolute value equals "the inside" when "the inside" is non-negative, and equals " (-) the inside" when "the inside is negative So you need to find where "the inside" is zero (i e find the roots of $-2x^3 + 24x = 0$ and possibly split the integral into two or more $\endgroup$ –
