Trigonometric_教師DEMO密版

Although the new outline of the trigonometric function until the second year to teach, students learn or confused, the teacher hard to teach, teach the complete chapter trigonometric function, you may find that students can not answer sin120 value. Students do not work, or the traditional teaching method is not attractive? What can attract the attention of the students, I use the game to make students skilled special angle of the trigonometric function value.
雖然新綱把三角函數延到高二才教，學生還是學得一頭霧水，老師賣力教，教完整章三角函數，可能發現還有學生答不出sin120的值。是學生不用功，還是傳統教法沒有吸引力？甚麼最能吸引學生的注意力，我用遊戲來讓學生熟練特殊角的三角函數值。
