1. The problem statement, all variables and given/known data A separable differential equation is a first-order differential equation that can be algebraically manipulated to look like: a. f(x)dx +f(y)dx b. f(y)dy = g(x)dx c. f(x)dx = f(y)dy d. g(y)dx = f(x)dx e. both f(y)dy=g(x)dx and f(x)dx = f(y)dy 2. Relevant equations 3. The attempt at a solution B is the way it is defined in the book so I assume that is the answer, but "e" gave me pause. I feel like the two equations in "e" are not the same but I can not explain why they are different. I have the feeling knowing that would help fill in some of the pieces between memorizing how to do this stuff and really understanding it. Then again if I am off and the answer may be "e". Can anyone shed some light?
