1. Prerequisites
Before you study calculus, it is important that you have a mastery of the concepts that come before it. I found calculus difficult to master (I basically had to take Differential and Integral Calculus three times in a row!), and I think many students also find it challenging -...
Hi guys,
I have been self-studying physics since sometime Its been going great,but I was reading yesterday on magnetism their some stuff that my book doesn't cover and assume you already know how to do it.
For example If we place a compass between two mangetic field or three or more we need...
Dear friends of MHB
in this thread some aspects of the difference equation of degree greater than one are investigated. For size limitation the tutorial is divided into several sections. As for the part I, suggestions, observations, requests of clarification and improvements are welcome...
I want good tutorial on programming fractals using computer languages like C++,Java,Python,C#,Perl,Delphi,OpenGL.
I want to program various fractals using any above languages for that I need some tutorial.
Please suggest me some of the resources which are useful.
Dear friends of MHB
some months ago I wrote for MHF a tutorial on the Difference equations and the reason of that was the difficulties I noticed in the treatment of difference equations, an important chapter of Discrete Maths that [may be...] is a little unfairly undervaluated. Request by the...
Hi all,
Back on MHF, my Differential Equations Tutorial was beneficial to many members and I was proud of my contribution to the site. However, with the fall of MHF, I have not been able to retrieve my old posts. So my plan is to start a completely new one on this site -- from scratch. I...

I've been working with python for about 4 or five months. I understand how to use boolean, a little bit of I/O, making functions, writing my own classes, and importing modules. Pretty much the bare basics. Outside of this python experience, I have little knowledge of programming. So, can...

I need to program an Atmega8 chip to handle various tasks, and while the teacher on the subject is pretty good, the text we use is hilariously bad. Is there a good textbook on the subject which is widely available, or do you know a good online tutorial?
Does anyone know of a good Precalculus Tutorial Dvd, or maybe a course that streams the classes on the Internet, like MIT does with OpenCourseWare? Thanks
