Mysterious figure.

[Steve W]

Dear mathematicians,

A maths graduate friend of mine sent me a letter recently, after I'd been telling them of my interest in maths, and - long time ago - moderate knowledge in some areas.

At the end of the letter, after the signature, they had drawn this figure, with no explanation at all: -



What the heck might that mean?

About all I know (I think) is that there is a point of inflection at the origin? Does the "Q" symbol have some special significance? Anything to do with quantum mechanics or some famous, or esoteric, maths problem? Anyone got a clue?

All suggestions would be gratefully appreciated. I don't want to look like a total ignoramus the next time I see them.

All best wishes

Steve

the drawing is the graph of \(\displaystyle y=x^3\) or \(\displaystyle x\) Q'bed you might say... I wouldn't say that but you or your friend might

Thank you very much for this insight Romsek! Too flipping clever for the likes fo me.

Thank you for fixing your error....almost no one does that.

Hi Romesk, could the solution also be the pun "tan Q" ?

Hi Romesk, could the solution also be the pun "tan Q" ?

Well I can't claim to be any sort of universal authority on the what goes on in your friends brain I would say sure, it could.

Actually looking at it now that's probably exactly what it is.
