I know yahoo had intended it to be more of a science subject instead of a belief subject but the modern popularity of the Paranormal is really a belief and not a science.

Just wondering how those of you who are actually in the science field or similar training feel about this.

Thankyou to everyone who put me straight on the moons synchronus rotation around its own axis and not the earths.
My son is very happy to be an IOU millionaire at 13 ! ( see my original question)
As I understand it, the slowing of the moons `natural` speed of rotation was caused by the earth and moons gravitational pull.
If the moon were to break free of the earth`s pull would it start spinning quicker, stay the same or fly off like a rock.
Ah you can see I`m still a bit sceptical. So the crux of my question is how do we know it is still rotating. after all this time in synchronous orbit how do we know it hasn`t just stopped

For the first one, I know pi = 3.14somethingsomething but I'm stuck on everything else. Can you pull that out of the integral sign because it's a constant?

The second one I actually solved!!! Is this right:
(cos3x)^5 = [(cos3x)^6] /6 *times* -sin3x

I have a feeling I'm wrong.
