Yes, that is awesome Ngai, wouldn't that save me time in an exam! I really have to learn little tricks like that to make the questions quicker and easier, I've been learning a few clever substitutions that help with conics at the mo.

Thanks for those solutions...and for using sub and superscript, because I know how to do it now, didnt realise there was bb code for that.

Ngai = awesome.
