A partial derivative of a multivariable function is the rate of change of a variable while holding the other variables constant For a function z = f ( x, y), {\displaystyle z=f (x,y),} we can take the partial derivative with respect to either x {\displaystyle x} orAny suggestions would be really appreciated01 Recall ordinary derivatives If y is a function of x then dy dx is the derivative meaning the gradient (slope of the graph) or the rate of change with
