# Calculus Chapter.1 Notes

## Chapter 01, Real Numbers, Limits and Continuity

Calculus Chapter 01 Real Numbers, Limits and Continuity Notes for Exam Preparation. These calculus notes were created using the most recent BSc/ADS course. We are aware that the BSc math syllabus is extensive and many students are unaware of its completion date. You can now go to Study Medium to access all of the calculus chapters. Because a professional writer created these notes, you can prepare them all without worry.

Both rational and irrational numbers are considered to be real numbers. Real numbers include all rational and irrational numbers, including integers (-2, 0, 1), fractions (1/2, 2.5), and the number 3. A function f with variable x is continuous at point “a” on the real line if the limit of f(x), when x approaches the point “a,” is identical to the value of f(x) at “a,” which indicates that f is continuous (a).
