Yeah wasn't sure whether to or not. I'm not sure how 1st year uni maths differs from uni to uni, but assumed it would be similar. So everyone can just post their math problems and get help here [or mods can move it wherever best].Good idea - perhaps this thread should be moved to the UNSW science faculty sub forum though?

How is R^2 different to R? (and by R I mean the special R/real numbers).
I'm watching Kahn academy videos on vectors. I'm understanding everything so far, the guy is using (x,y) notation, but then suddenly switches to a different notation I'm not familiar with. This happened in my class lecture as well.
Can someone help me understand what this notation means:
That notation with a vertical arrow is used to refer to a vector. Typically, e.g. in MATH201 at UOW, this notation is used to refer to row vectors; although it can be used to refer to column vectors as in the case here.I'm watching Kahn academy videos on vectors.

(edit: Integrand already answered this)
I guess that's just for the vector a etc.Some of the math tutors\lecturers at USYD refer to the arrow notation as the "Russian way" of writing it. Apparently the normal westernised one is basically a squiggly line that's under the letter.

How do I do the last parts of these questions. I understand the rest, but have no idea what to do when it comes to throwing in epsilon in there (the last questions/s).
i think you should ask the maple consultant that's on tomorrow morningHow do I do the last parts of these questions. I understand the rest, but have no idea what to do when it comes to throwing in epsilon in there (the last questions/s).
are they suppose to help with actual questions or just how to use maple?i think you should ask the maple consultant that's on tomorrow morning
i hear he's pretty awesome
