Step-by-Step Solution
Solution:
Step 1: Calculate vector x values
linspace(0, 2, 5)creates [0, 0.5, 1, 1.5, 2].Step 2: Compute y = sin(pi * x)
Calculate sin(pi*0)=0, sin(pi*0.5)=1, sin(pi*1)=0, sin(pi*1.5)=-1, sin(pi*2)=0.Final Answer:
[0 1 0 -1 0] -> Option AQuick Check:
sin(pi * linspace(0,2,5)) = [0 1 0 -1 0] [OK]
Quick Trick: Calculate linspace values first, then apply sin(pi * x) [OK]
Common Mistakes:
- Confusing degrees and radians in sin function
- Miscomputing linspace values
- Using wrong function like cos instead of sin
