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)
elif discriminant == 0:
x = -b/(2*a)
return (x,)
else:
return "No real solutions"
# Example usage:
print(quadratic(1, -3, 2)) # Output: (2.0, 1.0)
2. Numerical Integration
def integrate(f, a, b, n=1000):
h = (b - a) / n
total = 0.5 * (f(a) + f(b))
for i in range(1, n):
total += f(a + i*h)
return total * h
# Example: Integrate x^2 from 0 to 1
result = integrate(lambda x: x**2, 0, 1)
