Taking Discrete Mathematics in August (Help)

AI Thread Summary
Taking Discrete Mathematics after a long break from math can be daunting, but focusing on algebra and proof techniques is more beneficial than reviewing calculus. Discrete math emphasizes reasoning and logic over traditional calculus concepts, with an early focus on statements and truth values. Engaging with the textbook and practicing problems will enhance understanding. Utilizing forums for questions and support can also aid in the learning process. Emphasizing rational thinking and spatial reasoning will be key to success in this course.

Hi all,

I am going to be taking Discrete Mathematics in August and my last Math course was about 5 years ago. I am a little intimidated to just 'jump' back into Math especially a course like this one.

Can anyone who was successful give me a few pointers? I ordered the Textbook and will start reviewing, I am also looking in my old Calculus books just to sharpen my mind some.

Thanks

Hi bigk, :smile:

In my opinion, reviewing calculus will be useless here, since discrete mathematics doesn't really use much calculus. Instead, review some algebra and review proofs (if your discrete math was like mine, then you'll encounter many proofs!).

The good thing about discrete mathematics is that it's very unlike other math classes. You won't be calculating derivatives and integrals, but you'll be reasoning a lot. Reviewing your new textbook should really help you. And don't forget posting any questions you have here on PF :smile:
 
A proper discrete math course should begin with a discussion of logic, what it means for something to be a statement and what it means for a statement to have a truth value. You'll have fun drawing truth tables.

In fact, thinking back on my discrete class, we did not utilize any knowledge from Calculus until the very end of the course. Most of the material required being comfortable with algebra and the possession of an ability to think rationally and spatially.
 
Thank you for the input! I will definitely be coming to physics forums for my questions. In the past I would usually just search and find my relevant question.

I guess I will start with reviewing all of my Algebra and begin to think more rationally! :approve:
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
