Do you care to expand on what you mean by if it's Inconvenient?

The amount of effort is not commensurate to the reward if I prove it.

Personally i feel that if you cannot prove it or show me good odds that it is probably correct then i do not know how you can possibly believe it.

Just because this is such a trite internetism, 

Cos^2(X)=1-Sin^2(X)
Cos(X)=sqrt(1-Sin^2(X))
1+Cos(X)=1+sqrt(1-Sin^2(X))
1+Cos(pi)=1+sqrt(1-Sin^2(pi))
1-1=1+sqrt(1-0)
0=2

If you looked at that result (not that 2 actually equals zero but that I have just disproved pythagorean identities) and disbelieved it without immediately knowing the mathematical error I intentionally made, congratulations, you now know how it feels to be religious. Please grab a habit or whatever those nun hats are called on your way out.

EVERYONE (read: everyone) believes in that which cannot be proven. The Munchausen trilemma: A conclusion must have as its premises

1. An axiom (a premise accepted without proof because it cannot be proven)
2. An infinite regression of proof (impossible)
3. A premise it itself proves (circular logic is inherently fallacious.

To illustrate the trilemma, ask someone to prove something obvious, do your best impresion of a five-year-old and ask "How do you know?"
