Solving problems through answering my own question [duplicate]

I recently found some solution to some integral, I want to share some methods that may help people who are new to calculus. Can I make my thread kind of like a tutorial, or is that off-topic or will it be closed by the moderators?

For example: Title: How to solve the integral of $$x^2$$. Answer: A tutorial about the power rule $$\frac{x^{n+1}}{n+1}$$ (Not that basic but I don't want to type the full thing)

Is this type of thing allowed and if not, what can I do with the "Answer your own question – share your knowledge, Q&A-style" checkbox?

• Sorry for being circumspect, but the first thing to do is make sure that the post you intend to create is not a duplicate. This may not be the case in general, but looking at your example, I feel like there is probably some duplicate lying around explaining the power rule well. Dec 3, 2021 at 16:33
• Ok so even after searching no duplicates, if I do it this way, will it be closed for "off-topic"? The actual thing im thinking about writing is about normal distributions of that sorts.

• Without being too picky about duplication : If I trust you when you say you are not posting a duplicate, then what I'd like to see is your post coming out. I don't expect it to be closed as off-topic, if your question follows the guidelines. There is always one option if you're a little concerned : let me know what question you have, or go over here to the constructive feedback chatroom if you have trouble after posting your question. Call me there, and we can discuss issues. Sometimes, these surface only after posting. Dec 3, 2021 at 16:45
• Its about taking the integral of the normal distribution function using 2 different methods.
