Chapter 4. Higher-Order Di ff erential Equations § 4.6 Variation of Parameters We study linear nonhomogeneous DEs in the form of y + P ( x ) y + Q ( x ) y = f ( x ) where P ( x ) , Q ( x ) and f ( x ) are continuous functions. The general so- lution of the DE is y = y c + y p where y p is a particular solution and y c is the general solution of the corresponding homogeneous DE and y c = c 1 y 1 + c 2 y 2 where y 1 and y 2 are two linearly independent solutions to homogeneous

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
