Y = ln x then e y = x Now implicitly take the derivative of both sides with respect to x remembering to multiply by dy/dx on the left hand side since it is given in terms of y not x e y dy/dx = 1 From the inverse definition, we can substitute x in for e y to get x dy/dx = 1 Finally, divide by x to get dy/dx = 1/x We have proven theSolve the given differential equation by separation of variables y ln(x) dx dy = y 1 x 2A first order Differential Equation is Homogeneous when it can be in this form dy dx = F ( y x ) We can solve it using Separation of Variables but first we create a new variable v = y x v = y x which is also y = vx And dy dx = d (vx) dx = v dx dx x dv dx (by the Product Rule) Which can be simplified to dy dx = v x dv dx
