Hi ice109,
Thank you for your response.
What I really want is the quantity \frac{\partial z}{\partial x}=\frac{\partial f}{\partial x}+\frac{\partial f}{\partial g}\frac{\partial g}{\partial x}.
\frac{\partial f}{\partial x} does not reflect the second term above.
But do I have to...
Hi All,
I have a question about notation.
Suppose I have an expression:
f(x,g(x,y))
I would like to know how to express (not calculate) the rate of change of the above expression with regards to x.
I can always express it like this:
Let z(x,y) = f(x,g(x,y)). Rate of change is...
