I gave this one a shot, and the code works. Am I on the right track? How can the code be improved? Also, I am unaware of how to determine if this would be linear time or not. Could someone maybe break that determination down for me? ”’ Problem statement: Find pairs in an integerRead more

I have a simple function f(x)= t [0.216019, 0.216971]. How do I tell the software to divide this interval into 10 equal intervals (and also to give me their values)?Read more

I haven’t worked on XSL. Scenario: We have a list which has a column called expiry. We want to display only those records which have expiry date greater than or equal to today’s date. Trials: After n number if trials and googling have found out how to set a XSL variable today’s date <xsl:variable name=”curDt”Read more

While setting up a new phone for a family member whose location I want to track and calendar to manage (yeah, Big Brother type for medical reasons), I logged from my phone to her google account as an additional account. So in most google apps and sites I have this dropdown like who am IRead more

Imagine a LineSegment class that represents a line segment using two arbitrary endpoints. Should the constructor throw if it is passed two approximately equal endpoints? Obviously this would require some arbitrary floating point comparison. For example, test the Euclidean distance between the endpoints is less than ε. An advantage is users aren’t going to getRead more

As I understand it, $ i^i$ returns more than one real number. Why does this happen? When I raise $ i$ to $ i$ , I’m raising a specific number to itself. So why do I get multiple values of this, as if it was, for lack of a better word, some sort of aRead more

I want to stitch images using equal cameras(Point Grey GS3-U3-41C6C-C) but with different lenses. One lense is a wide-angle lense (Sunex DSL318B-650-F2.4) and the other is a fish-eye lens (Fujinon FE185C086HA-1). This setup is from the 360° camera of facebook. The overlapping area for the stitching is more that enough so there should be noRead more

The command SameQ[1, Null] returns False which is what I would expect, but the command Equal[1, Null] returns 1==Null Why is Mathematica agnostic as to whether 1 is equal to Null ? Surely it is not ?Read more
