高中数学中的反三角函数与三角方程问题对学生来说是一个难点,因为学生在高中数学中先学习三角函数,后学习反三角函数,会出现先入为主现象.学生容易将反三角函数与三角函数混淆.由于学生对反三角函数知识理解和掌握得不好,势必影响三角方程的学
Anti-trigonometry and trigonometric problems in high school mathematics are a challenge for students because students learn trigonometry first in high school mathematics and then pro-trigonometrical phenomena in learning high school mathematics. Students can easily associate trigonometric functions with trigonometric functions Confusion.Because of students’ understanding and mastery of the knowledge of the anti-trigonometry function, it is bound to affect the learning of trigonometric equations
