hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Check function and limits
from scipy import integrate import numpy as np result, _ = integrate.quad(np.sin, 0, np.pi) print(result) correctly imports numpy and uses np.sin as the function, with limits 0 to np.pi.Step 2: Analyze other options
import scipy.integrate as integrate result = integrate.quad('sin(x)', 0, 3.14) print(result) passes a string instead of a function; from scipy.integrate import quad result = quad(np.sin(0), 0, np.pi) print(result) calls np.sin(0) which evaluates to 0, not a function; from scipy import integrate result = integrate.quad(np.sin, 0, 3.14) print(result) misses import numpy as np causing NameError.Final Answer:
from scipy import integrate import numpy as np result, _ = integrate.quad(np.sin, 0, np.pi) print(result) -> Option BQuick Check:
Use function and exact limits for integration [OK]
Quick Trick: Pass function, not string, to integrate.quad [OK]
Common Mistakes:
MISTAKES- Passing string instead of function
- Calling function instead of passing it
- Using approximate constants instead of np.pi
