WebJul 7, 2024 · Can limits be undefined? Lesson Summary. Some limits in calculus are undefined because the function doesn’t approach a finite value. The following limits are undefined: One-sided limits are when the function is a different value when approached from the left and the right sides of the function. WebLet a = 1 and let b = 1. Obviously then, a = b is true since a=1 and b = 1 thus a = b means 1 = 1, which is true. Now multiply both sides of the equation a = b by a and we get: a·a = a·b, and we can rewrite that as a² = a·b. Now let us subtract b² from both sides of the equation so a²=a·b becomes: a² - b² = a·b - b².
