I am a PhD student majoring in Medical Engineering. My interest in Math is high, but my knowledge isn’t. I have just a bit of knowledge in Calculus, Linear Algebra and a little Statistics (just can do mean, median and mode). When I entered my PhD, I was really surprised at the complexity of the concepts we were expected to know, like SLAM, Green’s Theorem, Cholesky factorization, etc.
How can I catch up? The time constraint is really short (2 months), and I want to really understand all the concepts to the point where I can derive them. However, if I am stuck, I don’t want to see the answer since it makes me feel depressed and that makes me realize that I really lack in fundamentals.
I really like Mathematics, but after seeing a lot of Math problems on YouTube where I cannot even get close to the solution, I am questioning whether I am fit for Engineering or not.
