euler_84

Simple Euler's method utility for TI-84. Great for doing your B/C homework. ;)

Getting Started

Follow these instructions to use this utility on a physical TI-84 or an emulator with a TI-84 ROM image loaded. The one referenced in this ReadMe is jsTIfied, an online graphing calculator emulator that can be found at Cemetech.net.

Prerequisites

Calculator

TI Connect™ Software - Software for sending the program to the calculator
USB Mini B Cable - Cable connecting the calculator to the computer

Emulator

TI-84 ROM Image - A ROM image needs to be loaded onto the emulator for it to work

Installation

Use TI Connect™ to send the EULER.8xp file to your calculator. You can also read the code in the raw.txt file of the repository and manually write it on your calculator if you're familiar with TI-BASIC.

Usage

1.) Input the derivative expression in terms of X and Y into y₁ of the Y= window.

2.) Run the program EULER in the programs menu.

3.) Input values.

X(0) is the initial value of x
Y(0) is the initial value of y
X(N) is the target value of x
H is the step

Example

Use Euler's Method to approximate the value of y when x = 1 if y' = 3y-1 and y(0) = 1 with a step of 0.25.

X(0) = 0
Y(0) = 1
X(N) = 1
H = 0.25

Built With

TI-84 Plus - Calculator used to make the program
TI Connect™ Software - Used to export the program from the calculator to the computer in .8xp format
Source Coder 3 (Cemetech.net) - Simplifies debugging process
