Question 5 Numerical Approximation Methods basic ideas: Please write the basic idea (with key equations), application example, advantages and limitations of the following numerical approximation methods for solving linear/nonlinear equations. Please also state cases/examples for which one method can provide good result, but other may not. 1) Relaxation method 2) Binary search method 3) Newton's method 4) Secant method [Note: You can use simple examples for showing their applications. You might not need to derive any method]
Please answer the following and ignore the previously written answer; B) Alice thinks a better way to model the dorm (keeping the field order from part a) is to change the first field to the following.

# dates and times with lubridateinstall.packages("nycflights13") library(tidyverse)library(lubridate)library(nycflights13) Qustion: Create a function called date_quarter that accepts any vector of dates as its input and then returns the corresponding quarter for each date Examples: “2019-01-01” should return “Q1” “2011-05-23” should return “Q2” “1978-09-30” should return “Q3” Etc. Use the flight's data set from the nycflights13 package to test your function by creating a new column called quarter using mutate()
Problem Statement: The mathematician Conway imagined a game, called game of life, whichconsidered cells that are susceptible to reproduce, disappear, or survive when they obey certainrules. These cells are represented by elements on a grid of squares, where a grid has an arbitrarysize. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squaresthat contain other cells. The rules are stated as follows:1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation.Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation.Write a program that simulates this game and displays all successive…
