There are certain tips for these questions :
  1. Logarithmic functions, Trigonometric functions, and inverse Trigonometric functions are differentiable in their domain.
  2. Every polynomial function, exponential function & constant function is differentiable at each point of the real line.
  3. If a function is not differentiable but is continuous at a point, it geometrically impliesthere is a sharp corner or a kink at that point
  4. If a function is differentiable at x = a, then it is continuous at that point but vice versa is not always true.

Dear student,
The best trick to do any maths question is to practice a variety of problems.
