Key Topics to Revise

1

Understanding Limits

  • A limit describes the value a function approaches as the input approaches a certain point.
  • The limit exists only if the left-hand limit (LHL) and right-hand limit (RHL) are equal.
  • The value of the function at the point is not necessary for the limit to exist.
2

Continuity of Functions

  • A function is continuous at a point if the limit exists and equals the function's value at that point.
  • Discontinuities can be removable, jump, or infinite, each with distinct graphical features.
  • Polynomial, trigonometric, exponential, and logarithmic functions are continuous in their domains.
