comment Isomorphism between sets in affine spaces
No worries. The previous question was in the comments. As for your current question, just search the site. This has been asked before.

comment Isomorphism between sets in affine spaces
I typed an answer to your previous question (why $V(y^2 - x) \cong \mathbb A^1)$, just to notice that you've changed it now. Not cool. Your current question has been answered on this site before.

comment Isomorphism between sets in affine spaces
The question is wrong. $V(y^2 - x) \cong \mathbb A^1$ and $V(xy - 1) \cong \mathbb A^1 - \{0\}$, but $\mathbb A^1 \not \cong \mathbb A^1 - \{0\}$.

comment what does it mean by k* here?
Hi Kenneth, would you please typeset your questions instead of posting photos? Photos, especially ones taken from weird angles like this, are difficult to read and aren't searchable. Here is a tutorial.

comment The injectivity of $f\mapsto f\circ v$ on $\hom(M'',N)$ implies that $v$ is surjective
Have a look at the question I linked to. It has the answer to your question.

comment How to compute $\int \frac{x}{(x^2-4x+8)^2} \mathrm dx$?
@anorton Let's keep it civil, shall we? All what I'm saying is that the answers presented here are merely special cases of a general solution we already have on this site. The reason we have a generalized answer is precisely to avoid a proliferation of special cases that don't add value. Given how straightforward it is to apply the general solution to this case, I doubt that there is value in waiting for new methods.

@anorton If there is a method not mentioned in the general answer, it should be added there.

comment How to compute $\int \frac{x}{(x^2-4x+8)^2} \mathrm dx$?
@anorton Do you have an answer to the OP's second question that isn't a subset of the generalized answered posted by Peter? We have generalized answers for a reason.

comment How to compute $\int \frac{x}{(x^2-4x+8)^2} \mathrm dx$?
@amWhy The OP asked for a more general case. The answers below don't answer that. I think it is a duplicate.

Your English is OK. Where does this question come from? Do you have any thoughts on how to approach it?

Did you try using the fundamental theorem of Calculus?

comment Can the boundary of a subset be open?
While this is true, the boundary can be open and closed at the same time. These are not mutually exclusive properties.

comment Programming string in math
@jcubic I don't understand the question. What do you mean by language theory? If you're looking for the analogue of string in formal languages, then it's called a word.
