Programming Examples
Here are some practical Python programs you can run on the TI-84 Plus CE-T:
1. Quadratic Equation Solver
from math import sqrt
def quadratic(a, b, c):
discriminant = b**2 - 4*a*c
if discriminant > 0:
x1 = (-b + sqrt(discriminant))/(2*a)
x2 = (-b - sqrt(discriminant))/(2*a)
return (x1, x2)

return (x,)
else:
return "No real solutions"
# Example usage:
print(quadratic(1, -3, 2))
2. Data Analysis with Lists
def analyze_data(data):
total = sum(data)
average = total / len(data)
data_sorted = sorted(data)
median = data_sorted[len(data)//2] if len(data) % 2 else \
(data_sorted[len(data)//2 - 1] + data_sorted[len(data)//2]) / 2
return {"sum": total, "average": average,
"median": median, "min": min(data), "max": max(data)}
# Example usage:
test_data = [12, 15, 18, 14, 22, 19, 17]
print(analyze_data(test_data))
3. Simple Game: Number Guessing
from random import randint
def guess_number():
number = randint(1, 100)
attempts = 0
while True:
guess = int(input("Guess a number (1-100): "))
attempts += 1
if guess < number:
print("Too low!")
elif guess > number:
print("Too high!")
else:
print(f"Correct! You took {attempts} attempts.")
break

Tips for Effective Programming on the TI-84 Plus CE-T
- Optimize Your Code: The calculator has limited resources, so avoid unnecessary computations and optimize loops.
- Use Calculator-Specific Modules: Take advantage of TI’s Python modules that interface with calculator functions for better performance.
- Manage Memory: Break large programs into smaller modules and clear unused variables to conserve memory.
- Leverage the Display: Use the color screen effectively for data visualization and user interfaces.
- Test Incrementally: Test small sections of code as you develop to identify and fix issues early.
- Document Your Code: Good comments and documentation are especially important on a device with limited screen space.
- Backup Your Programs: Regularly transfer your programs to a computer to prevent data loss.
Limitations and Workarounds
While powerful, the TI-84 Plus CE-T Python Edition does have some limitations:
- Limited Python Version: The calculator runs Python 3.4, which lacks some features of newer versions. Workaround: Write code that’s compatible with 3.4 or simulate missing features.
- Memory Constraints: Large programs may run slowly or fail. Workaround: Optimize code and break programs into smaller parts.
- No Internet Access: Cannot import online libraries. Workaround: Pre-load necessary libraries or write your own implementations.
- Input Methods: Text input is slower than on a computer. Workaround: Use program editor features and template code.
- Limited Screen Size: Displaying complex outputs can be challenging. Workaround: Use scrolling and pagination in your programs.
