In advanced mathematics, we will talk a little about analytic geometry, mainly using calculus to study geometric problems, such as tangent, normal, curvature of curve, tangent plane of surface and so on. What chapter of the book do you want to read ... there is no unified textbook in universities ... generally it is used as an application of calculus.
Linear algebra may also involve some geometry, such as geometric transformation from the perspective of linear transformation, conic/quadric surface classification from the perspective of quadratic form, etc. (If linear algebra is not learned or difficult to learn, this part will be gone ...)
If you are an engineering student, you will generally learn descriptive geometry, that is, how to represent a three-dimensional diagram on a plane. This is the most like middle school geometry! It has a lot to do with ruler painting.
If you like to look at pictures, there are many pictures ... all kinds of curves in economics ... but many of them are qualitative, so it is good to understand the geometry intuitively ~ ~
Generally speaking, letters, numbers and formulas are the main subjects in college mathematics class, but in many cases, good geometric intuition is very helpful to assist understanding!
In the mathematics department of the university, geometry is also a big piece, but it feels completely different from middle school ... Since LZ is not in the mathematics department, I won't talk about it ~ You can ask me if you are interested:)
One more thing: the physics department said it alone! ! Physics sometimes has more mathematical knowledge than mathematics department. ...
