If y = (2 ⁻¹ x) then dy dx = ..

Options

  1. A2 - 4x^2 1 - x^2
  2. B2 + 4x^2 1 - x^2
  3. C2 - 4x^2 1 + x^2
  4. D2 + 4x^2 1 + x^2

Correct answer

A. 2 - 4x^2 1 - x^2

Step-by-step solution

Given y = (2 ⁻¹ x) Differentiating with respect to x using the chain rule: dy dx = (2 ⁻¹ x) d dx (2 ⁻¹ x) dy dx = (2 ⁻¹ x) 2 1 - x^2 Using the trigonometric identity (2 ) = 1 - 2 ^2 , we can write: (2 ⁻¹ x) = 1 - 2 ^2( ⁻¹ x) = 1 - 2x^2 Substituting this back into the derivative: dy dx = (1 - 2x^2) 2 1 - x^2 dy dx = 2 - 4x^2 1 - x^2
