The particular solution of the differential equation y ( d x ~d y )=x x at x= e and y =1 is

Options

  1. Ae ^ x y =2
  2. Bx= e ^ y
  3. Cx y =2
  4. Dx=2 y

Correct answer

B. x= e ^ y

Step-by-step solution

(D) y ( d x d y )=x x 1 x x d x= 1 y d y | x|= y+ c We have x=e and y=1 | e|= 1+ c c=0 | x|= y x=y x=e^ y
