Chinese translation:正切半角換元or正切半角換元法
Explanation:
Sure in mainland China, "substitution" could be translated into 变量替代/变量代换。
But “换元”=变量替代/变量代换, which is more concise.
And if you are not discuss the method itself, "法"is not always necessary.
When you just do the substitution, 正切半角換元or正切半角換元法are both good.
