Express d t d x = t (x+t e^ -2 x / 4 ) in the form of d x d t = ( x t )

Options

  1. Ax t +e^ -2 ( x t )
  2. Bx t -e^ -2 ( x t )
  3. Cx t +e^ 2 ( x t )
  4. Dx t -e^ 2 ( x t )

Correct answer

A. x t +e^ -2 ( x t )

Step-by-step solution

d t d x = t x+t e^ -2 x t On reciprocal, we get d x d t = x+t e^ -2 x t t = ( x t )+e^ -2 ( x t ) Hence, option (1) is correct.
