Markov Chains Prob 2 Page 413 In Example 11.4, let \(a=0\) and \(b=1/2\) Find \(P\), \(P^{2}\), and \(P^{3}\) What would \(P^{n}\) be? What happens as \(n\rightarrow \infty\)? Solution: \(P=\begin{pmatrix}(1-a) & a\\ b & (1-b)\end{pmatrix} = \begin{pmatrix}1 & 0\\ 1/2 & 1/2\end{pmatrix}\) \(\implies P^{2} = \begin{pmatrix}1 & 0\\ 1/2 & 1/2\end{pm...

Assignment 6: D3 lab D3.js is a powerful data visualization library. Rather than being based around existing plot types, d3 allows you to bind any html element. This power is a double edged sword. It allows you to build completely custom data visualizations, but because you're dealing with individual html elements, you're forced to interact with ...

Question 01 Use integration by substitution to solve the integral below. \(\int4e^{-7x}dx\) Solution: Let \(u=-7x\) \(\implies\) \(dx=-\frac{1}{7}dz\) \(4\int e^z \frac{-1}{7}dz=\frac{-4}{7}\int e^zdz=-\frac{4}{7}e^z+C=-\frac{4}{7}e^{-7x}+C\) Question 02 Biologists are treating a pond contaminated with bacteria. The level of contamination is cha...

library(pracma) This week, we’ll work out some Taylor Series expansions of popular functions. f(x)=1/1-x For each function, only consider its valid ranges as indicated in the notes when you are computing the Taylor Series expansion. Please submit your assignment as a R-Markdown document. \[f\left( x \right) = \frac { 1 }{ (1-x) } \] \(f(a) + {...

Problem 1 Random Variables Using R, generate a random variable X that has 10,000 random uniform numbers from 1 to N, where N can be any number of your choosing greater than or equal to 6. Then generate a random variable Y that has 10,000 random normal numbers with a mean of\(\mu=\sigma=\frac{N+1}{2}\). # generating random numbers set.seed(4242)...
