Evaluate the Limit
Problem
Solution
Identify the form of the limit by substituting the value
x=1 into the expression.Evaluate the numerator as
x approaches1
Evaluate the denominator as
x approaches1
Analyze the behavior of the fraction. Since the numerator approaches a non-zero constant (
1 and the denominator approaches0 the limit does not exist as a finite number.Determine the one-sided limits. As
x→1 ln(x) is positive and approaching0 so the expression approaches+∞ Asx→1 ln(x) is negative and approaching0 so the expression approaches−∞
Conclude that because the left-hand and right-hand limits are not equal, the two-sided limit does not exist.
