Key Topics to Revise

1

1. Differentiability at a Point

  • A function is differentiable at a point when the derivative exists finitely there.
  • A function is differentiable at x = c if the right-hand and left-hand limits both exist finitely and are equal.
  • A function is non-differentiable at x = c if it is not differentiable at x = c.
2

2. First Principle and Meaning of Derivative

  • The first principle defines derivative using a small increment h.
  • The derivative of a function at x is written as f'(x).
  • dy/dx is another notation for derivative of y with respect to x.
3

3. Basic Rules of Differentiation

  • The derivative of a constant is 0.
  • The derivative of x^n is n x^(n-1).
  • The derivative rules for sum, difference, scalar multiple, product, power of function, and quotient are essential for fast calculation.

4. Standard Derivatives and Special Results

  • The derivative of sin x is cos x.
  • The derivative of cos x is -sin x.
  • The derivative of tan x is sec^2 x.
