psets & exams. not the easiest exams but nice curve and also gives hints if you are stuck on problems

I learned how to work in a group to complete problems, how to prove problems and pay close attention in lecture.

Professor Dragomir was passionate about teaching and accommodating in lectures and OHs. I wish the course was more organized, such as giving assignments in more consistent time manner. 1 Columbia University: Arts & Sciences Spring 2023 Course: MATHUN2015_001_2023_1-LinearAlgebraandProbability : MATHUN2015_001_2023_1 - Linear Algebra and Probability Instructor: George Dragomir

Vector operations, Vector functions, Space curves, Quadric Surfaces, fundamentals of functions of multi-variables, imagining in R3.

Topology, Advanced Linear Algebra, mathematical research.

Basics of calculus II -- integrals, sequences and series, applications of single variable calculus

Calculus 1 skills -- derivatives and intergrals

one of the best math professors i've had. you know he cares about his students. super friendly and approachable. the content of the course is not easy if you are new to number theory and sometimes it can be difficult to understand, but he definitely tries his best to explain things as simple as possible. his office hours before every exam are super important, sometimes the exact problem he goes through will be on the exam and he will tell you that.

I learned about linear algebra from a rigorous proof-based perspective during this course. We focused on set theory, vector spaces, matrices, and other key topics in linear algebra.

The course content is useful, but the teaching style did not work super well for me. It was also more work with proofs than I was expecting. 1 Columbia University: Arts & Sciences Fall 2022 Course: MATHUN2015_001_2022_3-LinearAlgebraandProbability : MATHUN2015_001_2022_3 - Linear Algebra and Probability Instructor: George Dragomir
