Limits and Continuity Exercise 2.1

This example demonstrates the concept of limits and continuity at specific points for a function, involving core mathematical ideas such as limits, continuity, special points, sine function, standard deviation, normal distribution, and upper and lower sums or Riemann sums. The construction highlights the use of GeoGebra commands to create the function object f, with slider animations to visualize the limit process and analyze continuity/discontinuity at various points. Suitable for introductory calculus students or those reviewing related concepts.
