That's the same as vdv=dx isn't it? I mean isn't y'''' the derivative of y'''?
Same dif if is was yy'=1 or y'y'' and so forth.
I am new to this forum. I think that you are doing a very good job here helping people solve their problems !!!!
In few days i have one of my final course exam (I will graduate) and i have some questions that concerns me
One of them is this :
I had an idea to put y'''=u , y''''=u' but it didn't worked
How can i solve this ???
Thanks in advance
