Guide to posting special characters

Inserting mathematical symbols vectors and variables
♦ Vectors are denoted by variables in bold: to make text bold, type
<B>This text will be bold</B> when typing a comment or post.
All other variables are denoted by italics: <i>Text will be italic</i>
♦ Powers are bracketed by <sup></sup> and subscripts by <sup></sup>.
♦ Mathematical symbols, Greek letters etc. are inserted by typing the HTML code or name for them. Here is an exhaustive list of maths symbols, Greek letters etc. and their codes.
E.g. if I wanted to type part of the Kerr black hole metric I would enter
<I>ds</I><sup>2</sup> = &hellip; 2<I>a</I>sin<sup>2</sup>&theta;(<I>r</I><sup>2</sup> + <I>a</I><sup>2</sup> - &Delta;)/&Sigma; <I>dtd&phi;</I> &hellip;
which comes out as: ds2 = … 2asin2θ(r2 + a2 - Δ)/Σ dtdφ
NB for the HTML-savvy: To show HTML code, the pre and code tags don't appear to work: instead use &lt;tag&gt;&lt;/tag&gt; and &amp;char; for special characters.
