Hello! Desperately looking for an answer to this. While it's not really a physics or maths question, I don't really know where else to ask, so I reasoned here was as good as anywhere - please excuse me if I'm asking in the wrong place. Does anyone recognise the font used in this integral? I'd like to download it and use it for myself, but I can't find it anywhere. Is there a .ttf (or equivalent) for it? (I'm not yet a proficient Latex user, so I'd struggle with getting fonts working though that.) I much prefer this style of integral sign to the slanted ones used in Computer Modern and Cambria Math. Thanks.
