E-Code2-D steady conduction, plate series — a TI-84 Plus CE program
PLATE2D is a TI-BASIC program for the TI-84 Plus CE. Rectangular plate, three sides at zero and the top at a uniform temperature rise: separation-of-variables series at any point.
What it asks for and what it shows
It asks for 5 values at its prompts. In the example below it shows T(X,Y), T MID, T/DT.
Example run
One of its oracle test cases: “square centre”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Input 1 | 1 |
| Input 2 | 1 |
| Input 3 | 100 |
| Input 4 | 0.5 |
| Input 5 | 0.5 |
| The screen shows | |
T(X,Y)= | 25 |
T MID= | 25 |
T/DT= | 0.25 |
How it's checked
3 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 13 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “2-D steady conduction, plate series” (PLATE2D).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
