comment Is this probability question wrong to begin with?
My reasoning would be along the lines that the answers given do not pertain to the question, and any mulitple choice question with 4 answers gives you a $25$% chance. So both A and D would be acceptable answers. Good question in general, though! (+1)

comment Showing a vertical tangent exists at a given function.
as a side note, if you would like to learn LaTeX, there exists a very helpful guide here on our meta site. There is also a stack.exchange site for TeX and LaTeX called tex.stackexchange if you have any questions or would like to go into specifics about it.

comment Can I keep adding more dimensions to complex numbers?
The properties of the number $i$ don't "break" the properties of the real numbers, they expand on them in a way that allows for square roots of negative numbers to be actual values.
