Has anyone ever personally seen a baby pigeon? And not someone who raises them, I mean like outside in "the wild". I live in Brooklyn, and all I ever see are those little brown birds (not sure what they're called) and fully grown pigeons. I know that they nest on tall buildings, but come on now.....how can I never have seen at least one baby pigeon in nearly 30 years of living in New York, the pigeon capitol of the world??

the problem is worked out, but i need to find out how. The book is not very helpful in explaining this.

numerator is x^4 - 8x
denominator is 3x^3 - 2x^2 - 8x

The answer is given as:
numerator: x^2 +2x +4
denominator: 3x +4

What i mean is how can pi be infinite...because if it were then in theory a circle could never be measured because the ratio would always be expanding. Like this

Circle A has a diameter X and a Circumference Y the ratio should be Pi; but if you work it backwards Pi times Y then it would never equal X because Pi could not be defined as a number.. You know what I mean.....
