Is there some command to find the fixed points of a function F(y)?. As my intuition suggests me.. it would not be possible to get the the values x such that x=F(x) for a general function, but.. which commands should I look at to get the values of x for a specific F (I would like to see that in the case of x is in R4.. that is x= (x1, x2, x3,x4)? Any answer will be really appreciated. J

I would like to represent the frequency of the output (values of x, values of y) of the following commands.. restart: with(stats): with(Optimization):stats[random, normald](1); for i from 1 to 10 do z:= Maximize(1/3*ln(x)+1/3*ln(y), {x+y

I want to evaluate the limit as sigma=0 of the integral from -infinity to +infinity of V(t)*f(t) where f(.) is the normal density. I think that I must obtain V(mu) but I only get: "lim sigma->inf of integral etc etc. " The "commands" that I did use are: restart; > MyFunc1:=(t,sigma,mu)->int(V(t)*1/2*2^(1/2)/Pi^(1/2)/sigma*exp(-1/2*(t-mu)^2/sigma^2), t=-infinity..+infinity); >limit(MyFunc1(t,sigma, mu), sigma=0); Probably I am doing something wrong, because I am almost sure that MAPLE can do it. Could somebody please point my mistake or suggest any hint? Thanks a lot. JV
