Which of the following is the correct syntax to compute the integral of
cos(x) from 0 to pi using integral?Which of the following is the correct syntax to compute the integral of cos(x) from 0 to pi using integral?
easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Understand function handle syntax
MATLAB requires function handles forintegral, written as@(x) cos(x).Step 2: Check syntax correctness
integral(@(x) cos(x), 0, pi) correctly uses anonymous function handle; others are invalid syntax or strings.Final Answer:
integral(@(x) cos(x), 0, pi) -> Option AQuick Check:
Correct integral syntax uses function handle = integral(@(x) cos(x), 0, pi) [OK]
Quick Trick: Use @(x) for anonymous function handles in integral [OK]
Common Mistakes:
- Passing function name without @
- Using strings instead of function handles
- Calling function inside integral arguments
