WebJul 30, 2024 · Intuitive Definition of a Limit. Let’s first take a closer look at how the function f(x) = (x2 − 4) / (x − 2) behaves around x = 2 in Figure 2.2.1. As the values of x approach 2 from either side of 2, the values of y = f(x) approach 4. Mathematically, we say that the limit of f(x) as x approaches 2 is 4. WebNov 11, 2024 · To evaluate the limiting value of x log ( e x − 1) − x 2 as x approaches 0, there's no problem with approaching 0 from below too since then also the function is defined properly and real. Thus as x vanishes, we get 0 ⋅ log ( 1 − 1) − 0 = 0 ⋅ ( − ∞) = 0. The first summand also vanishes since we may write this as x 1 / log ( e x − 1), WebNov 16, 2024 · If we can find two paths upon which the function approaches different values as we get near the point then we will know that the limit doesn’t exist.
