I'm studying calculus III topics on my own, but I've seen this notation prop up a lot. Could you tell me what it means?
http://en.wikipedia.org/wiki/Exact_differential
The notation on this page, it has this notation:
[tex]( \frac{dA}{dx} )_y = ( \frac{dB}{dy} )_x[/tex]
What do the x's and y's mean as subscript of the parenthesis? Just plug in the y value at that point into that derivative's equation?
