We covered the product rule in maths last lecture, and as part of the derivation of it, we got this line:
[tex]\frac{\partial y}{\partial x}=\frac{u \partial v}{\partial x} + \frac{v \partial u}{\partial x} + \frac{\partial u \partial v}{\partial x}[/tex]
And were told that as [tex]x \rightarrow 0[/tex]
[tex]\frac{\partial u \partial v}{\partial x}[/tex] just "goes away".
Can anyone explain why this is so?
(edit: quite pleased with my first attempt at tex :D )
