Understanding Limits and Indeterminate Forms

The video tutorial explores the limit of x over the natural log of x as x approaches 1. It begins by explaining the properties of limits and evaluates the numerator and denominator separately. The numerator is straightforward, as the limit of x as it approaches 1 is simply 1. However, the denominator, the natural log of x, evaluated at 1, results in zero, leading to an undefined expression of 1/0. The video concludes that the limit does not exist due to this undefined form.

What is the main problem discussed in the video?

• Finding the limit of x over natural log of x as x approaches 0

• Finding the derivative of x over natural log of x
