Key Concepts in Calculus: Rate of Change

NettetYou have already seen (I hope) that whenever you have “variables” you need to consider change of variables. Random variables are no different. The notion of “change of random variable” is handled too brieﬂy on page 112 and 115 (the meaning of the symbol h(X) is not even deﬁned in the text). This is something I will test you on ...

NettetDerivatives of a Function of Two Variables. When studying derivatives of functions of one variable, we found that one interpretation of the derivative is an instantaneous rate of change of y y as a function of x. x. Leibniz notation for the derivative is d y / d x, d y / d x, which implies that y y is the dependent variable and x x is the NettetThe partial derivatives of a function tell us the instantaneous rate at which the function changes as we hold all but one independent variable constant and allow the remaining independent variable to change.
