When it comes to modeling a phenomenon or an experiment, it is often necessary to obtain equations that involve the 'variations' of the quantities (variables) present and considered essential. Thus, the laws governing such a phenomenon are translated into equations of When these variations are continuous, the mathematical equations are called equations, whereas if the variables involved are functions of a network of points, where we have the averages of the variations, then the equations that describe the phenomenon will be called difference equations. Considering your knowledge of Differential Equations (EDO) Separable, judge the statements below as (V) True or (F) False.

dy/dx = 3xex can be written as dx = 3x dy/dx
dy/dx = y/3 can be written as dx = (1+y)^2 dy
The separable equation dy/dx = x^3/(1+y)^2 can be written as dx = (1+y)^2 dy
The equation dy/dx = (1+x)^2 can be written as dx = dy/(1+x)^2
