1. The problem statement, all variables and given/known data 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. 2. Relevant equations I have no idea what to do in order to solve this. 3. The attempt at a solution dy/dx=y2 -y dy/dx= y(y-1) ∫dy/y=∫(y-1)dx ln(y)=y-1?? eln(y)=e(y-1) y= ey-1 I don't think this is write, but this is what I have... can someone help?
