Revision Notes — Continuity And Differentiability
Key concepts, formulas, and definitions from Continuity And Differentiability for CUET (UG) Mathematics preparation.
Key Topics to Revise
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)
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
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
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
