Note that for this problem, we're told to take the derivative with respect to one particular variable. This is known as taking a partial derivative; often it is denoted with the Greek character delta, , or by the subscript of the variable being considered such as  or .

For a problem like this, where we presume all variables are independent of each other, we need only consider the variable that we're taking the derivative of the function with respect to; all other variables can be treated as constants.
