近几年的数学教学发现技校学生大都表现为对数学平面几何、三角函数、解析几何的计算能力较差,可是对于数控专业的学生来说更是离不了数学计算和数学作图,因为数学作图知识比抽象的理论知识更直观,以动手操作为主,能直观形象的表现一些数学公理、定理及数学 In recent years, mathematics teaching has found that most of the technical school students show poor computational ability for math plane geometry, trigonometric functions and analytic geometry. However, it is even more difficult for students majoring in numerical control to math and math. Figure knowledge is more intuitive than abstract theoretical knowledge, which is mainly hands-on, which can intuitively represent some mathematical axioms, theorems and maths
