One basic identity that involves the intersection shows us what happens when we take the intersection of any set with the empty set, denoted by #8709. The empty set is the set with no elements. If there are no elements in at least one of the sets we are trying to find the intersectio...
Theintersectionof any set with the empty set is the empty set. This is because there are no elements in the empty set, and so the two sets have no elements in common. In symbols, we writeX∩ ∅ = ∅. Theunionof any set with the empty set is the set we started with. This is...
Lauren Yoshizawa (LY): My answer to this question draws on two different areas of my work. Most of my previous research has been positioned at the intersection between school improvement efforts and research use. The conventional way of understanding the role of research in supporting school impro...
If one removes sets from the picture, then one no longer has immediate access to arbitrary elements of a set, and one can no longer perform operations en masse on all the elements of a set at once; instead, one must use some (possibly more restrictive) protocol for manipulating objects ...

Also if you track calculations with a 'paper tape' on a PC its far easier to manipulate.For school, learning math concepts and being that some classes do not allow you to use a PC, PC provides far better graphing capabilities, you have to go with what the class recommends.Title: Re: ...
The other answers are quite good, just one detail to understand it: O(log n) or similar means, that it depends on the "length" or "size" of the input, not on the value itself. This could be hard to understand, but is very important. For example, this happens when your algorith...
I know in physics we really like to wonder what things really represent and how the math really connects with the real world. In mathematics however, generalisation and abstraction lead to connections between things that would be difficult if studying them at face value. ...
