     Tim, sorry, I'm now lost with this... I recognise it though. I think our teacher
showed us the same?

    I could do with someone taking me through the basics again... Are you game? I'd
appreciate it.

   If it's ok, mail me or take me through it here, either way, no probs. I used to
enjoy doing trig. when I was younger.
