Homogeneity, although knowledge itself is not important, but the school has a clear goal for the cultivation of students. In a limited time, it is necessary to make appropriate choices about what you have learned in order to better serve this major. For non-mathematics majors, the demand for calculus, algebra and probability statistics exceeds that of geometry.
Third, most of the knowledge of geometry was learned in middle school.
Perhaps with the development of science and technology to a certain period, the role of geometry has become very important, so geometry will replace a part of mathematics and enter the classroom of non-mathematics majors.
