well yes i do have a sense of humour and i think its key to have one.

I am studying at glyndwr university, wrexham formally know as NEWI.

I had a maths exam yesterday which didnt go to plan

and i have a mechanics exam tomorrow which i have been studying for night and day. (this exam will be on calculating stresses and strains on materials at given points, working out other variables mainly from equations and formulae.) I have never been taught how to transpose formulae apart from the old triangle method for simple 3 variable ones such as :-

V=

__D__
T

where you cover the one you want with ur finger leaving you with what you want...hard to explain but how i was told to do it...

tomorrows exam has transposition of formula on so was looking for a calculator to do it for me and help me out. If not any advice on manipulating the equations?
