M427K Final Exam Name NO NOTES. NO CALCULATORS. 1. Find the general solution of y 0 - 2 xy = x. 2. Use the method of undetermined coefficients to find the general solution of y 00 - y 0 - 2 y = 4 x 2 . 3. The function y = 1 is a solution to ty 00 - 2 y 0 = 0 . Find another solution and show it’s linearly independent to the first solution. 4. Let u ( x, t ) be a function of two variables. If possible, use the method of separation of variables to write u xx + u tt + 5 u = 0 as two different ordinary differential equations. 5. Use Laplace transforms to solve the IVP: y 0 + y = sin( x ) , y (0) = 1 . 6. Find the eigenvalues and eigenfunctions of the BVP y 00 + λy = 0 , y (0) = 0 , y 0 (4) = 0 . 7.

### 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.
