Different choices of definitions can be specified using the option FourierParameters.Other definitions are used in some scientific and technical fields.Now the answer to the same problem would be False. Buy WolframAlpha plus educational and professional apps for iOS, Android and Windows phones. Suppose though I wanted the domain to be positive integers Z +. Note that the zero frequency term appears at position 1 in the resulting list. In Wolfram Alpha I could put: Resolve ForAll n, ForAll m, Exists p, p (m+n)/2 and it correctly comes back with True as a result since there is a real number p for any real values m, n.The discrete Fourier transform v s of a list u r of length n is by default defined to be u r e 2 π i ( r- 1 ) ( s- 1 )/ n.The remaining 2 were formal logic which I was never really taught. I got linked to a HS exam a few months ago and could for all but 2 questions confidently say "This is how you solve it" even if some specifics were gone (like sine cosine multiplication rules etcet) Access data and computations when and where you need them, optimized for mobile and touch devices. The stuff I was always weakest at (arrays notably) are also weakened.īut I still feel I have both a good grasp and good intuition. Buy WolframAlpha plus educational and professional apps for iOS, Android and Windows phones. The term 'discrete mathematics' is therefore used in contrast with 'continuous mathematics,' which is the branch of mathematics dealing with objects that can vary smoothly (and which includes, for example, calculus ). Stuff like FT which I did a lot of practical stuff with shortly after I was instructed remains in my mind. Discrete mathematics is the branch of mathematics dealing with objects that can assume only distinct, separated values. I looked at QM work I did 20y ago and just see symbols being moved around.Īnything below it has been so ingrained to get to that level that it stays with me forever. I still remember the concepts, and the outcomes, but come nowhere close to reproducing it. I lost the top layer, the things I did in the last years of uni.
