解反三角函数题是学生感到困难的问题,究其错误的产生,常是由于忽视反三角函数的定义域和主值区间。现就几个例子来探讨常见的错误。 [例1]:当|x|≤1、|y|≤1时,求证
Resolving inverse trigonometric problems is a problem that students feel is difficult. The reason for their mistakes is often due to neglecting the domain of definition and the main value interval of the inverse trigonometric function. Here are a few examples to discuss common mistakes. [Example 1]: When |x| ≤ 1, y| ≤ 1, verify
