- 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 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
- 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
- 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

- Indefinite double integral - Mathematics Stack Exchange
In calculus we've been introduced first with indefinite integral, then with the definite one Then we've been introduced with the concept of double (definite) integral and multiple (definite) integ
- What is the integral of $e^ {\cos x}$ - Mathematics Stack Exchange
This integral is one I can't solve I have been trying to do it for the last two days, but can't get success I can't do it by parts because the new integral thus formed will be even more difficult to solve I can't find out any substitution that I can make in this integral to make it simpler Please help me solve it
