Dec 5 accepted Math book for engineer from the functions to the integrals Dec 5 asked Encyclopedic dictionary of Mathematics Dec 2 awarded Teacher Dec 2 comment Techniques for visualising $n$ dimension spaces you say it right "theorist", Preet Sangha is looking for a pratical solution not theories. The human knowledge has switched from geometry to analitical analysis much time ago, the analisys is good when we have to dial with complex problems but is pratically impossible to visualize over N>3, this is the price to pay for us. Also do not confuse the terms, usually the physicist use the verb "describe" and not "visualize" when they talk about N dimensions. Dec 2 answered Techniques for visualising $n$ dimension spaces Dec 2 comment Proving that an integral means “potential” in physics terms You are close to my topic but not to what my teacher says. How many definitions are available for the integral operator ( i'm referring this question to the first line of your reply )? We never have treated the potential as a function but as system, a linear system that sometimes we develop with a matrix or with classic algebra calculus, and the integral gives us a quantity that can rapresent the total amount of energy available in a system, i am not talking about law or function, i only consider the integral as an operator that can quantify the potential as result. Where i'm wrong? Dec 1 comment Proving that an integral means “potential” in physics terms what are your doubts? I'm considering a generic integral, an infinite sum of infinitesimals. Dec 1 asked Proving that an integral means “potential” in physics terms Dec 1 comment Metric System vs Imperial System: general considerations about algorithms and college math i'd like to ask to you the same thing as above about the existence of a dedicated branch studying this kind of problems. Dec 1 comment Metric System vs Imperial System: general considerations about algorithms and college math In your knowledge there is no such thing like a "dedicate discipline" like the numerical analysis for the numerical stability, there is a part of the math dedicated to this kind of problems? Dec 1 comment Metric System vs Imperial System: general considerations about algorithms and college math @austin-mohr why? Dec 1 asked Metric System vs Imperial System: general considerations about algorithms and college math Nov 29 asked Math book for engineer from the functions to the integrals Nov 29 comment The derivative is a real limit? ok, assuming that it's a long story for a topic on the internet, at least i like to have the right big picture in mind, could you say what are the theorems that i can try to revisit to better understand this with this particular approach about the calculus ? Nov 29 comment The derivative is a real limit? ok, but considering a more generic approach, what about trascendental function? what about when an order of magnitude is difficult or impossible to define? I made an example about a really simple function, also i know for sure that this a crescent function and it's always positive, how can i know more about this kind of approach with derivatives and limits, something that can be applied to each and all the several families of functions? Nov 29 awarded Student Nov 29 comment The derivative is a real limit? @kahen what do you mean with that? It's a solution that does not fit all the common needs about the infinitesimal calculus? It's not always precise? Can you provide a more complete post?
