Math 2450 Week 5 Limit of a function with several variables Z = f(x,y) 3 D: |R R : |R Domain and Range is real for all real numbers; Cases for limits (2D) 1) Hole in a function lim f(x) = L- - xx o lim f(x) = L+ + xx o - + if L + L = L then lim f(x) = L xx o 2) Break in a function Limit DNE Formal Definition of a limit in one Dimension For every ε >0 there exist a δ > 0 such that |x – o | < δ , x not equal to x | f(x) – L | < ε Translation: For every epsilon greater than zero, there exist a delta greater than zero such that the magnitude of the change of x is less than delta and where x is not equal to x no
