SciPy - Constants and Special Functions

What is the output of the following code snippet?

from scipy.special import jn
values = [jn(0, x) for x in [0, 1, 2]]
print([round(v, 3) for v in values])

A[0.0, 1.0, 2.0]

B[1.0, 0.765, 0.224]

C[1.0, 0.0, -1.0]

D[0.5, 0.5, 0.5]

Step-by-Step Solution

Solution:

Step 1: Understand jn(0, x) values
jn(0, x) is the Bessel function of order 0. At 0 it equals 1, then decreases.
Step 2: Calculate approximate values
jn(0, 0) = 1.0, jn(0, 1) ≈ 0.765, jn(0, 2) ≈ 0.224 after rounding.
Final Answer:
[1.0, 0.765, 0.224] -> Option B
Quick Check:
jn(0, x) values match [1.0, 0.765, 0.224] [OK]

Quick Trick: Order 0 Bessel at 0 is 1, then decreases smoothly [OK]
