Where am I going wrong here?!?
Find the general solution of the following equation;
So, my working.
Using the whole (ry)' = ry' + r'y = r(y' + py) = rf thing where p = 2/x and f = x^2...
The answer given in the tutorial is (no working given) and I have no idea how to get that though I figure the problem lies with the log bit... Any help?
Only thing is, i have a resit in methods of applied maths in a few days and one of the things i did wrong on the first exam was that thing where you use the (ry)' = rf thing and i know thats what you've sort of done here but i need to know where i go wrong in my working above.
