- What is an integral? - Mathematics Stack Exchange
A 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
- What is the integral of 1 x? - Mathematics Stack Exchange
Answers 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
- What does it mean for an integral to be convergent?
The noun phrase "improper integral" written as $$ \int_a^\infty f (x) \, dx $$ is well defined If the appropriate limit exists, we attach the property "convergent" to that expression and use the same expression for the limit
- How do you find the primitive integral of $\arctan (x)$?
I tried searching for how you derive the integral primitive of $\arctan (x)$, but I can't find any question on S E with an answer that clearly explains this I feel that there should be one, since it is rather fundamental knowledge, and it does come up every now and then as part of S E questions
