Thread: Just some question

Im just curious, nothing too serious really, but i want to ask, how hard do you consider this question from a student's view ( not some expert university student etc... maybe around 16 yrs old)

prove the following;



just a throw of opinions really, thanks

harder than anything i got at school

I only did maths to high school level (A Higher 'B' for those familiar with the Scottish system of the 1960s.) I couldn't have done this then. I wouldn't even know where to begin now.

You got a cheat sheet with all the trig identities?

Off the cuff, this strikes me as either a very silly question to pose to else there is some subtle trick which I don't see at the moment.

I can't imagine where such an equation arises naturally.

If it will make you feel better there is a mathematics legend, probably true, that during World War II some very high-powered mathematicians were working on an aerodynamics problem that involved a nasty trigonometric relationship. They studied it for some time, sending communications back and for by airplane, before finally discovering that the whole mess reduced to 1. I think that Abraham Robinson was one of the mathematicians involved.

i think the subtle trick involved is;
