The number of solutions of the equation s i n - 1 x = sin ⁡ x - 1 is/are

Options

  1. Aone
  2. Btwo
  3. Cthree
  4. Dzero

Correct answer

B. two

Step-by-step solution

∵ sin ⁡ x - 1 = 1 sin ⁡ x = cosec ⁡ x Now, from graphs of sin - 1 ⁡ x , cosec ⁡ x Clearly, both graph intersects at two points ∴ two solutions
