I have posted a partial solution set to problem set 1 on the assignments page of the math 101 website (which you are already at if you are reading this). It is available in DVI, PDF and PostScript formats so one of the three ought to work for everybody. I've also posted the original LaTeX source in case anyone is curious about that. If there's some other format that anyone would like to have solution sets posted in just let me know and I'll see what I can do. (Word is out of the question since it just can't handle real mathematical type-setting---the same goes for all other conventional word processing programs.)
