The video tutorial covers the concept of infinite limits, evaluating limits of functions like 1/x and 1/x^2 as x approaches zero, and provides examples of one-sided limits. It also explores limits involving trigonometric functions such as tangent and cosecant, and explains how to find vertical asymptotes in rational functions.
