finding the crosspoint(?) of two functions

hey guys, i don't know if i've used the right term (crosspoint)..
i need to find the point where these two functions meet.

f1(x)=lnx
f2(x)=x^2/2e

f1(x)=f2(x)
y=?

i'm pretty sure that i have to use "ln" on this but i'm not very good with LNs so please help

Re: finding the crosspoint(?) of two functions

it may not be solved "exactly", i guess


X'(y-Xβ)=0

i just need to find the point where they meet. without that i won't be able to calculate the size of space these two functions "embrace."
