comment All homogeneous rings of a projective variety
Thanks Arturo, I considered that but was too lazy. :P

comment Separating points in the plane by a compact set that is not allowed to intersect a given set A
This is trickier than I thought. :D

comment Which simple puzzles have fooled professional mathematicians?
This is pretty similar to this question: math.stackexchange.com/questions/250/… not the same but similar

comment How can I calculate the transformation of two 3D triangles?
I am so sorry but I am still confused as to what you are asking. I am ok with the definition of your triangle ABC. But I still don't know what you mean by transformation.

What do you mean the triangle has transformations? I thought maybe you meant symmetries, but I don't see how a translation will give a symmetry, so I am clueless.

comment Generator of a group
I should mention that this was not in our actual course. It was supplementary lectures. I can envision a nice course where free groups come fairly naturally. Either based on D&F or just in general.

comment Generator of a group
my personal experience was that I learned them smack dab in the middle of my group theory course, just before rings. I found them to be super intuitive, and they made me realize I was not understanding some things about groups that I though I had.

comment How can I calculate the transformation of two 3D triangles?
I don't understand your parenthetical remarks. Is your question "How do calculate a linear transformation of one given triangle into another?" If so, what is the rotation and translation part of your question? Also, if that is your question, you can calculate it by change of basis formulas.

comment Generator of a group
I think that this is the correct approach. Seeing that groups are the quotients of the free group really clears up group presentations and prepares one for other algebraic structures.

comment geometric construction of a given angle
J.M.'s link will undoubtedly help you move towards your question. But just a reference if you want a nice soft introduction is Howie's Fields and Galois Theory. I find his treatment of constructibility to be very nice. However I notice that Dinesh added the (relevant) tag "field-extensions". Which means I don't know your background. You should edit your question to include more information about your background so that we can help you more than pointers to resources(or at least make sure those pointers are the right pointers).

comment How to prove the q-series identity?
I'm sorry, could you define your notation here? Maybe everyone else knows it, and if so then it's fine, but I'm not sure about it. Sorry if this is stupid.

comment Is there a definitive guide to speaking mathematics?
I think you need to be more specific. I for one, don't understand what the text would look like or what sort of standard you are thinking of.
