    Linearizing a Non Linear Differential Eq

    Sorry I might have written the questions wrong, first part is separate from the second part. The questions below are the right ones 3a.Use a suitable substitution to transform the nonlinear DE (dy)/(dx)+y=y² into a linear equation in the new variable z. 3b.without solving the DE, justify the...

    Linearizing a Non Linear Differential Eq

    Homework Statement Use a suitable substitution to transform the nonlinear DE (dy)/(dx)+y=y² into a linear equation in the new variable z. and without solving the DE, justify the possible methods that can be used to solve the DE found in first part. Homework Equations I have no idea what to...

    Non Separative Diff-EQ problem

    I understood what you did there, but it still gives me y= -c*e^(-x)+x-1, the negative in front of the constant still technically makes the answer wrong. But Thanx for your help. I appreciate it.

    Non Separative Diff-EQ problem

    The problem I'm given is - I think this is a non separable equation dy/dx=x-y ... u=x-y I tried Substituting, where x-y=u 1-dy/dx=du/dx (remember above statement u=x-y, and dy/dx=x-y) therefore, I got 1-u=du/dx and then I solved it from there by...
