If ( ⁻¹ (x²+y² )= ) then ( d y d x ) is equal to

Options

  1. A( - x y )
  2. B( x y )
  3. C( y x )
  4. D(-x y )

Correct answer

A. ( - x y )

Step-by-step solution

Given that, ( ⁻¹ (x²+y² )= ) ( x²+y²= ) Differentiating with respect to ( x ), we get [ array l 2 x+2 y d y d x =0 d y d x = -x y array ]
