A rectangle has an area of 24 m2 and one of its sides is 3 m long. What is the perimeter of the rectangle?

Yes??? Smile

Two of the angles in trapezium ABCD are right angles and one of the other angles measures 54°. What does the fourth angle measure?

Smile

Are those easy?

Let's hit harder Smile

What's the geometrical meaning of the central extension of the algebra
of diffeomorphisms of the circle? Razz

Hmm let's work this off :

"The Collatz Conjecture" aka "The 3X + 1 problem".
Let f(x) be a function defined on the positive integers such that:

f(x) = x/2 if x is even
f(x) = (3*x+1)/2 if x is odd

Then the conjecture is: Iterates of f(x) will eventually reach 1 for any
initial value of x.

:)Various cash prizes have been offered for the proof
or disproof of this conjecture. Smile
