常见例句

To answer that, you first need to calculate the norm of your quaternion .
答案在这，你首先需要计算你的四元数的平均值。
Quaternions make it possible to extend the concept of rotation in three dimensions to four dimensions (see Resources for links to quaternion references).
四元数可能把三维旋转的概念推广到四维（请参阅参考资料，其中有四元数的参考资料的链接）。
The answer to the obvious question is that q is a quaternion just when q = r + xi + yi + zi, where r is a real number, i is the square root of -1, and x, y, and z are complex numbers.
对于明显问题的回答是，仅当 q = r + xi + yi + zi 时 q 才是四元数，其中 r 是实数，i 是 -1 的平方根，x、y 和 z 是复数。
