If x and z are independent variables, then the function should be written as h(x,z), and the derivative with respect to z should be denoted by . In this case, x is treated a constant, so .
Thanks/ So variables are constants, unless they are taken with respect to the function?

thanks for replying! How would one know when the variable is a constant or not? See you have from the equation: and Why wouldn't
