First Derivative and Stationary Points - University of Sydney
The nature of stationary points The first derivative can be used to determine the nature of the stationary points once we have found the solutions to dy dx =0. Relative maximum Consider the function y = −x2 +1.Bydifferentiating and setting the derivative equal to zero, dy dx = −2x =0 when x =0,weknow there is a stationary point when x =0.

13 Introduction to Stationary Distributions
mast.queensu.caSo “stationary” refers to “stationary in time”. In particular, for a stationary process, the distribution of X n is the same for all n. So why do we care if our Markov chain is stationary? Well, if it were stationary and we knew what the distribution of each X nwas then we would know a lot because we would know the long run proportion of

From this we note that f x = 0 when x = 0, and f x = 0 and when y = 0, so x = 0, y = 0 i.e. (0,0) is a second stationary point of the function. It is important when solving the ...
