Although these calculations are nothing more than basic trigonometry and algebra, the formulas are very complicated.
虽然这些计算无非是最基本的三角形和代数计算，但是所使用的公式非常复杂。
Rather than explaining SLERP in detail here (it's really just basic trigonometry), I'll give you some source code in a minute.
与其在这里详细讨论球形线性插值而言(它只是些基础的三角学)，我宁愿稍后给你一些源代码。
Advanced math — XSLT can perform basic arithmetic easily enough, but it doesn't support trigonometry, exponential functions, logarithms, or other more advanced mathematical operators and functions.
高等数学——XSLT在基本数学方面游刃有余，但它不支持三角学、指数函数、对数或其他更为高级的数学运算符及函数。
