In ( 0 , 2 π ) , the total number of points where f x = m a x . sin ⁡ x , cos ⁡ x , 1 – cos ⁡ x is not differentiable, are equal to

Options

  1. A3
  2. B4
  3. C5
  4. D6

Correct answer

A. 3

Step-by-step solution

The graph of f x = m a x . sin ⁡ x , cos ⁡ x , 1 – cos ⁡ x is ⇒ f x is not differentiable at x = π 4 , π 2 , 5 π 3 . ⇒ f x is not differentiable at 3 points
