I am having difficulty trying to figure the following .
What is [tex] \frac{\mathrm{d} }{\mathrm{d} x}f(x,y) [/tex] where x is a function of s and t.
Here is my calculation [tex] \frac{\mathrm{d} }{\mathrm{d} x}f(x(s,t),y) = \frac{\partial f}{\partial x}\frac{\partial x}{\partial t}+\frac{\partial f}{\partial x}\frac{\partial x}{\partial s} [/tex]
Does this seem correct?
