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

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."
