請問數學會考孤度係咪out左syl?

請問數學會考弧度係咪out左syl?
聽人講係，又有人講唔係，其實係咪架？
參考香港考試局數學科課程綱要
第7頁12項「角之量度」說
僅以度為單位
那樣看來應該是 out左syl
雖然我覺得學一學也無妨

It is true that Radian measure had been removed from curent CE maths syllabus. In addition, formula of finding arc length and area of sector had also been removed. So you can learn radian measure in additional mathematics.

However, I think you should learn something about radian since in advanced maths and/or science, radian measure will be heavily used since its physical importance.
(One famous example is Calculus)
