Hi all,
This is not strictly a DE question, but I came across this while working on one. This isn't the first time I got this and I just can't remember this from my 1st year maths. Some knowledge would be greatly appreciated. In the answer they do the following:
(\frac{1}{x})(\frac{dy}{dx}) - (\frac{1}{x^2})y \Rightarrow<br /> <br /> (\frac{d}{dx})[(\frac{1}{x})y]
Now I want to know how? I just can't simplify it. Silly question, but need the help!
Thanks
