If (x+y)= (x+y) , then d y ~d x is

Options

  1. A2
  2. B1
  3. C0
  4. D-1

Correct answer

D. -1

Step-by-step solution

(x+y)= (x+y) Differentiating both sides w.r.t: x , we get aligned & 1 x+y (1+ d y ~d x )= (x+y) [1+ d y ~d x ] & 1 x+y + 1 x+y ~d y ~d x = (x+y)+ (x+y) d y ~d x & ~d y ~d x ( 1 x+y - (x+y) )= (x+y)- 1 x+y & ~d y ~d x =-1 aligned
