This is the integral that is sometimes described as "the area under the curve" (although I would consider that an application of the definite integral, not a definition).Tue, 31 Mar 2026 01:45:00 GMThttps://math.stackexchange.com/questions/206032/what-is-the-integral-of-1-xAnswers to the question of the integral of $\frac {1} {x}$ are all based on an implicit assumption that the upper and lower limits of the integral are both positive real numbers.Sun, 12 Apr 2026 05:12:00 GMThttps://math.stackexchange.com/questions/5123280/evaluate-an-integral-involving-a-series-and-product-in-the-denominatorEvaluate an integral involving a series and product in the denominator Ask Question Asked 1 month ago Modified 1 month agoMon, 06 Apr 2026 20:07:00 GMThttps://math.stackexchange.com/questions/586107/what-is-the-difference-between-an-indefinite-integral-and-an-antiderivativeWolfram Mathworld says that an indefinite integral is "also called an antiderivative". This MIT page says, "The more common name for the antiderivative is the indefinite integral." One is free to define terms as you like, but it looks like at least some (and possibly most) credible sources define them to be exactly the same thing.Sun, 12 Apr 2026 17:58:00 GMThttps://math.stackexchange.com/questions/15294/why-is-the-area-under-a-curve-the-integralOne is the question of why the definite Riemann integral gives the correct notion of "area under a curve" for a (nonnegative, Riemann integrable) function. The other, which seems to be what you're really asking, is the question of why an antiderivative evaluated at the endpoints of an interval and subtracted yields that definite integral.Mon, 13 Apr 2026 14:22:00 GMThttps://math.stackexchange.com/questions/1242056/solving-the-integral-of-ex2The integral which you describe has no closed form which is to say that it cannot be expressed in elementary functions. For example, you can express $\int x^2 \mathrm {d}x$ in elementary functions such as $\frac {x^3} {3} +C$.Thu, 09 Apr 2026 23:24:00 GMThttps://math.stackexchange.com/questions/2567170/what-is-an-integralA different type of integral, if you want to call it an integral, is a "path integral". These are actually defined by a "normal" integral (such as a Riemann integral), but path integrals do not seek to find the area under a curve. I think of them as finding a weighted, total displacement along a curve.Mon, 13 Apr 2026 11:30:00 GMThttps://math.stackexchange.com/questions/533082/integral-of-sqrt1-x2-using-integration-by-partsA different approach, building up from first principles, without using cos or sin to get the identity, $$\arcsin (x) = \int\frac1 {\sqrt {1-x^2}}dx$$ where the integrals is from 0 to z. With the integration by parts given in previous answers, this gives the result. The distance around a unit circle traveled from the y axis for a distance on the x axis = $\arcsin (x)$. $$\arcsin (x) = \int\frac ...Mon, 13 Apr 2026 17:07:00 GMThttps://math.stackexchange.com/questions/2660140/integral-int-sqrt1x2dxI was trying to do this integral $$\int \sqrt {1+x^2}dx$$ I saw this question and its' use of hyperbolic functions.
