Question
find the value of the summation.\\(\sum_{k=0}^{11} \sin(\pi k) =\\)
Step1: Evaluate term for k=0
$\sin(\pi \cdot 0) = \sin(0) = 0$
Step2: Evaluate term for k=1
$\sin(\pi \cdot 1) = \sin(\pi) = 0$
Step3: Generalize integer k rule
For any integer $k$, $\sin(\pi k) = 0$
Step4: Sum all 12 zero terms
$\sum_{k=0}^{11} 0 = 0 + 0 + \dots + 0$
