目前高职院校高等数学教学存在教师难教,学生难学的状况,学生对高等数学的学习缺乏兴趣与热情。问题的症结一方面在于高职学生数学基础差,学习兴趣不高;另一方面在于高等数学知识讲解千篇一律,改进力度不够、缺乏创新,对学生没有吸引力。现有三阶行列式的解法与空间平面位置关系的判定方法不易理解掌握,容易混乱,没有简单、明了的精简方法。原创“入”字法解三阶行列式与空间直角坐标系下点、平面位置关系口诀,方法简单,对数学基础要求低,口诀易学、易懂、易记,使用方便、高效。
At present, higher mathematics teaching in higher vocational colleges is difficult to teach teachers and students difficult to learn, students lack of interest and enthusiasm for advanced mathematics learning. On the one hand, the crux of the problem lies in the poor basic knowledge of majors and the low interest in learning. On the other hand, there is a lack of improvement in knowledge of advanced mathematics, lack of innovation and no appeal to students. The existing methods of determining the relationship between the solution of the third-order determinant and the position of the space plane are not easy to understand and grasp, and are easy to be confused. There is no simple and clear streamlining method. Original “Into ” Glyphs Solution Third-order determinant and spatial Cartesian coordinate system points, plane position relationship formulas, the method is simple, low on the basis of mathematics, formulas easy to learn, easy to understand, easy to remember, easy to use and efficient.
