If e^ =c+4 , where c is an arbitrary constant and is a function of , then what is d equal to?

Options

  1. Ad
  2. B- d
  3. C4 ~d
  4. D-4 ~d

Correct answer

B. - d

Step-by-step solution

aligned & e^ =C+4 & ( ) e= (C+4 ) & = (C+4 ) & g =4 ( )+ ( ) + C aligned Differentiating both sides with respect to ' '. aligned & + d d =4 ( 1 + 1 d d ) & d + d =4 d +4 d aligned aligned & 3 d =-3 d & d =- d aligned
