I posted this on our facebook wall awhile back and a few said there were errors. Can anyone find them?
It looks like 1/x and -1/x are incorrect, but if you use your imagination they work. I think the others are all good though.
edit: actually sinx is a graph of -sinx
The hands of tan x and cot x should be pointing up/down. Instead they look like they're deflecting (although the left hand of cot x looks OK).
[itex] \log_a(x) [/itex] is way off.
Needs to dislocate his shoulders more for [itex]y=a^x[/itex]. Some of those look quite painful for anyone who isn't some kind of tentacle monster.
Separate names with a comma.
