ello ello! I havn't seen an example of this type of problem. It has another variabler in the equation, i tried to divide by it, but its still in there. Here is the problem: Find y as a function of x if http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/ee/448e92b4900790fd8de8a4207ce40d1.png [Broken] http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/c9/0bc438e10b7ec37bb81942786780e41.png [Broken] y = ? So i divided by x^2 and got: y''+2y'/x -30y/x^2 = x; This kind of looks like an integrating factor problem but not. ANy suggestions or can someone explain to me whats going on? Thanks!
