Let a(n) = C(2n,n) / (n+1)
where C(2n,n) = (2n)Cn = (2n)! / (n!)^2

Let f(x) = ∑ a(n) * x^(n+1) * (1-x)^n
for 0 < x < 1, where n goes from 0 to infinity

Can anyone prove (or disprove) that
1) f(x) = 1 (constant) when 0.5 < x < 1
2) f(x) = x / (1-x) for 0 < x < 0.5 ?

I'm sure you can tell that the second statement is true if the first one is true.

...in this kind of question?

My attempt :

First, either both m and n are odd, or both m and n are even.

m^3 - n^3 = (m-n)(m^2 + mn + n^2) = 8+6mn = 2(4+3mn)

(and i'm stuck. As you can see, I haven't got a clue.)

6) A right triangle is a triangle with one angle measuring 90°. In a right triangle, the lengths of the sides are related by the Pythagorean Theorem, c2 = a2 + b2, where c is the length of the hypotenuse (the side opposite the 90° angle). Find the length of the hypotenuse when the other two sides’ measurements are 6 feet and 8 feet.
