Ya I'm pretty sure I've done it correctly in terms of finding min and max points of a function with two variables. Take the derivative with respect to each variable independently. and both ==0 you find the critical point. you can use various techniques to find out if its max or min. Edit...

Drawing the graph in 3d you see endless "mountains and valleys" which logic tells me there will also be infinite max min points in 2d regardless of where you slice the graph. apparently this is wrong and there is a finite max/min points in R^2/2D. Please note this problem does not have a domain...

problem i had was that they told me i can't eliminate terms unless I am transitioning fully off the limit. mixed signals.

is there a specific reason u kept the higher terms and removed the lower terms? is there a reasoning?

how many times do i have to take the derivative?

using Lhospital now yields no results.

is this correct?

the answer is not 0 it goes to infinity.

thanks i think this is a bit advanced for calc 101. ill try hospital instead. what do you think about that?

that is what I am thinking...thanks.

ok so a reflecton in xy plane is given by 100 010 00-1

i didn't get x^2...what are you talking about? the answer is infinite.

not really.

why not just multiple e^1/x into the bracket and convert all x->infinity at once?

this is calc 101... how many terms of e^ u taylor should i use?
