Continuity And Differentiability — Syllabus & Topics

Topics covered in Continuity And Differentiability for J&K CET Mathematics.

Topics in Continuity And Differentiability

1

Continuity of Functions

  • A function f(x) is continuous at x = a if lim(x→a) f(x) = f(a)
  • For continuity, three conditions must be satisfied: function must be defined at the point, limit must exist, and limit must equal function value
  • Continuity can be checked using left-hand limit (LHL) and right-hand limit (RHL)
2

Differentiability of Functions

  • A function is differentiable at x = a if both left-hand derivative (LHD) and right-hand derivative (RHD) exist and are equal
  • Differentiability implies continuity, but continuity does not imply differentiability
  • Common non-differentiable points: sharp corners, vertical tangents, and discontinuities
3

Derivatives of Inverse Trigonometric Functions

  • Inverse trigonometric functions have specific derivative formulas that must be memorized
  • Domain restrictions are crucial when working with inverse trigonometric functions
  • Chain rule applications are common with inverse trigonometric functions
4

Exponential and Logarithmic Functions

  • Exponential function eˣ is its own derivative: d/dx(eˣ) = eˣ
  • Natural logarithm derivative: d/dx(ln x) = 1/x for x > 0
  • Chain rule is frequently needed with exponential and logarithmic functions
