<p>Hey! I've been looking all over internet and couldn't find the right thing...
So is there any site that lists all the 'practical yet advanced' formulas/theorem for math?
such as Pick's theorem, Shoelace formula, etc..
and please don't tell me to search for random articles in aops...T.T
Thanks in advance! :D</p>
<p>To be honest there are TONS of useful mathematical formulas and even IMO winners don’t know them all. If you can get AOPS Vol2, Art and Craft of Problem Solving, enroll in an AOPS class, or do the intermediate AOPS series, that would be good. There are also many other books.</p>
<p>One way I have learned a few nifty formulas is through doing AIME problems and problems people post on AOPS forums. Master your basics first though - the specifics will soon follow.</p>
<p>Here is a great link for geometry and trig formulas though</p>
