I have several variables (coordinates) $x_1, x_2, x_3, x_4, z$ and a lot (21, to be precise) functions $g_i$ which are assumed to depend on $x_1, x_2,x_3, x_4$, but not on $z$. I also have a function
Differentiation which uses
Dt in its definition. I would like to apply
Differentiation to my functions $g_i$.
I found that this question proposed giving constants the attribute
"Constant". However, I cannot apply it directly, as my functions are constants only with respect to one variable.
Is there any way to do this?
