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? - Apr 7th 2012, 04:02 PMemakarovRe: differentiating with multiple variables

thanks for replying!

How would one know when the variable is a constant or not?

See you have from the equation:
