The video tutorial explains how to determine the value of K that makes a function continuous. It begins by discussing the concept of continuity and discontinuity in functions, using sine of X and linear functions as examples. The tutorial then demonstrates how to evaluate the left and right hand limits at a specific point, π, to ensure continuity. Finally, it shows how to solve for K by setting the left and right hand limits equal, concluding that K must be -2π for the function to be continuous.

What is the main goal of the problem discussed in the video?

• To determine if sine of X is a continuous function
