4th Order Rurka-Kutta Method
This assignment will expand your skills on using Excel to perform some numerical
analyses and plot your results. It is a means to familiarize you more with basic features in
the spreadsheet.
Preliminaries:
a. Start a new file called R-K.xlsx (for this exercise, you may use the work you did
in class but please be careful not to delete what you already have)
b. Plan ahead
Exercise 1:
Using the 4" Order Ruga-Kutta Method that we recently learned, evaluate the following
ordinary differential equation (ODE):
