Programming Examples
The Python implementation allows for sophisticated programs that would be difficult or impossible in traditional TI-Basic. Here are some practical examples:
1. Quadratic Equation Solver
from math import sqrt
def quadratic(a, b, c):
discriminant = b**2 - 4*a*c
if discriminant > 0:
root1 = (-b + sqrt(discriminant))/(2*a)
root2 = (-b - sqrt(discriminant))/(2*a)
return (root1, root2)
elif discriminant == 0:
root = -b/(2*a)
return (root,)
else:
return ("No real roots",)
# Example usage:
print(quadratic(1, -3, 2)) # Output: (2.0, 1.0)
2. Data Visualization
from ti_plotlib import hist, show_plot data = [1, 2, 2, 3, 3, 3, 4, 4, 5] hist(data, binwidth=1) show_plot()
3. Physics Simulation (Projectile Motion)
from ti_plotlib import *
def projectile(v, angle, steps=100):
g = 9.81
angle_rad = angle * 3.14159 / 180
vx = v * cos(angle_rad)
vy = v * sin(angle_rad)
x = [0]
y = [0]
t = 0
dt = 0.01
for _ in range(steps):
t += dt
x.append(vx * t)
y.append(vy * t - 0.5 * g * t**2)
if y[-1] < 0:
break
plot(x, y)
show_plot()
projectile(20, 45)
