Just (c) from the problem below:

1.11. Let f be a one-to-one smooth map of the real line to itself. One-to-one means that if f(xi) = f(x2), then x1 = x2. A function f is called increasing if x1 〈 x2 implies

f(x1 )くf(x2), and decreasing if x1 〈 x2 implies f(x1 ) 〉 f(x2 )

(a) Show that f is increasing for all x or f is decreasing for all:x

(b)Show that every orbit {x0, x1, x2…} of f2 satisfies either xo

x1x2… or xox1x2...

(c) Show that every orbit of f2 either diverges to +

or- or converges to a

fixed point of f2.

(d) What does this imply about convergence of the orbits of f?

Need this in C#. Below is my code for Problem 3 of Assignment 2. Just have to add the below requirement of calculating the expected winning probability of VCU. Revisit the program you developed for Problem 3 of Assignment 2. Now your program must calculate the expected winning probability of VCU through simulation. Run the simulation 10,000 times (i.e., play the games 10,000 times) and count the number of wins by VCU. And then, calculate the winning probability by using...
