This problem, I think, is a lot easier than it sounds. What is the formula I need? Any clever thinking also welcomed. ... The set {1,2,3,4} can be partitioned...
... Not all mathematics is formula-driven. Thinking is likely to get you farther with these questions. However, it may be helpful to know that the sum of the...
... Conway and Guy's "Book of Numbers" (which addresses similar issues at some length) seems a good reference to check regarding whether the result is new....
... I discovered a use of this property for factoring numbers, see my third post in the group that I set up: http://groups.yahoo.com/group/Figurate_Numbers...
Found this paradox in another group, but with no satisfactory solution: Thursday night a warden tells his prisoner, "You will be hanged one day at noon before...
Seems trivial enough. If a box contains 9 black socks and one white sock, you obviously won't be able to predict what colour sock is pulled from the box. But...
You can take the view as Quinne does (in the book "Ways of Paradox") that the warden is making a true statement, but that the prisoner has no way of knowing it...
pls i want u to help me with this question as fast as possible A light elastic string whose natural lenght is 0.4m carries a bob of mass 2kg at one end and...
A mass of 2kg located at a pointC is freely jointed to two equal light rods CA and CB, the end A of CA is pivoted to a fixed point A while B is freely jointed...
Regarding the tension. A kilogram mass exerts a force of 9.8 Newtons downward because the acceleration of gravity is 9.8 meters per second squared. So the...
Let s be the angle the string makes with the vertical, Fr is the radial component of the tension, w is the angular speed = 2pi a=w^2xr 1) Fr = mxa = 2w^2xr = 2...
It took me some time to interpret the geometry of this question. Triangle ABC is isoceles with AC = BC. AB is vertical. Let s be the angle the rods make with...
Because even though this group is steeped in fun, even to the point that fun transcends the very bits and bytes that compose it, in the real world there is ...
Amazing! What equation 4 says is that we don't need to know the angle, it drops out of all the equations. At first I did not believe this and proceeded to...
