Hi hi, due to no fault of my own I have ended up missing 2 of my lectures on partial differentiation. I have a friend who takes amazing note but unfortunately my lecturer only seems to go through examples rather than standard methods and formulas.(adsbygoogle = window.adsbygoogle || []).push({});

So could you please help me with a few things?

What is the chain rule in partial differentiation?

How do you work out the below?

[tex]\frac{ \partial g}{\partial x} \quad \text{for} \quad x^2 + y^2 = r^2[/tex]

And what do these mean please: [itex]F_{xx} \quad \text{and} \quad F_{xy}[/itex]

Thanks for any help you can give.
