Explanation: 
Another Explanation (5):
\( \hat{k} \times \hat{j} + \hat{j} \times \hat{k} \) এর মান নির্ণয়:
আমরা জানি,
* \( \hat{i} \times \hat{j} = \hat{k} \)
* \( \hat{j} \times \hat{k} = \hat{i} \)
* \( \hat{k} \times \hat{i} = \hat{j} \)
এবং \( \hat{j} \times \hat{i} = -\hat{k} \), \( \hat{k} \times \hat{j} = -\hat{i} \), \( \hat{i} \times \hat{k} = -\hat{j} \)
সুতরাং,
\( \hat{k} \times \hat{j} = -\hat{i} \)
\( \hat{j} \times \hat{k} = \hat{i} \)
অতএব,
\( \hat{k} \times \hat{j} + \hat{j} \times \hat{k} = -\hat{i} + \hat{i} = \vec{0} \)
সুতরাং, উত্তর: \( \vec{0} \) 🥳
