Note: make a graph of the solution for each solved problem. (For problems with more than one unknown parameter, draw the solutions taking one parameter 1 and the rest 0.)
Also solve the 4 questions below:
y'' + 2xy' - 2y = 0.
Note that y=x is one solution. Solution:Also: Make exam 3 of 1997. Give yourself 50 minutes. Include your solutions with homework set I and grade yourself using the solutions on the web after you get it back.
