I recently received some much-appreciated help from jobem and ahab with aspects of coding using trig.

It occured to me that there are probably lots of developers in my position, probably from non-techie backgrounds - serious mental block/gap when it comes to applied maths. Perhaps some of the moderators or anyone else could get together a tutorial/FAQ explaining this stuff from the ground up with direct relevance to Flash. I would certainly pay in cash for something like this...
