I'm stuck on a piece of work, I've done everything apart from the very last bit.
I need to prove something...
I have to show the equation...
( (x-1)^2 ) / ( (sqrt(3)) * (sqrt(x^4 + 4x^2 +1)) )
Is always between 0 andf 1 when x isn't 1.
In other words the denominator is always greater than the numerator.
It's quite clear and I can show it graphically, but I need a proof for it which I'm stuck with.
When I say proof, it's not going to be anything complex at all.
Any advice would be appreciated.
