@user079622 are you aware that these derivatives you have copied here are "partial derivatives" (that's why they have the curly "d" as in: ## {\partial f} ##)? The normal nomenclature is:user079622 said:Here is some different letters

##\frac {df} {dx}##, the derivative of function f with respect to x
##\frac {\partial f} {\partial x}##, the partial derivative of function f with respect to x
These are not the same, and if you do not know what a partial derivative is, that is OK, you just need to slow down and learn about "regular" derivatives first.
