Identify the error in this code that tries to compute the Bessel function of order 1 at 5.0:
import scipy.special
result = scipy.special.jn(5.0, 1)
AThe value parameter cannot be less than 2.
BThe function jn does not exist in scipy.special.
CThe order parameter must be an integer, not a float.
DThe import statement is incorrect.
Step-by-Step Solution
Solution:
  1. Step 1: Check parameter types for jn

    The order parameter for jn must be an integer, but 5.0 is a float.
  2. Step 2: Confirm function existence and parameter validity

    jn exists in scipy.special and value can be any float; import is correct.
  3. Final Answer:

    The order parameter must be an integer, not a float. -> Option C
  4. Quick Check:

    Order must be int, not float [OK]
Quick Trick: Order parameter for jn must be integer, not float [OK]
Common Mistakes:
MISTAKES
  • Passing float instead of int for order
  • Thinking jn is missing from scipy.special
  • Believing value must be above 2
