AI Thread Summary
The discussion focuses on solving the expression 1 + (√3 + 1)² / (√3 + 1). Initially, there is confusion regarding the correct approach, with users attempting to simplify the expression. After some back-and-forth, a clearer method is presented, leading to the conclusion that the expression simplifies to (5/2)√3 + (7/2). The final steps involve rationalizing the denominator and combining terms correctly. The resolution highlights the importance of careful simplification in algebraic expressions.

What are you trying to find?
 
\frac{1}{\sqrt{3}+1}+(\sqrt{3}+1)^2
is I believe what he was trying to get the answer to.

EDIT: Bah, read below...

I got \frac{5}{2}\sqrt{3}+\frac{7}{2}
 
What? Wait... d'oh! I forgot to divide the other half of the expression by \sqrt{3}-1... Seems like the whole thing doesn't work now...

Then you have to go about it like so:

\frac{1}{\sqrt{3}+1}+(\sqrt{3}+1)^2
=\frac{1+(\sqrt{3}+1)^3}{\sqrt{3}+1}
=\frac{(1+(\sqrt{3}+1)^3)(\sqrt{3}-1)}{(\sqrt{3}+1)(\sqrt{3}-1)}
=\frac{\sqrt{3}-1+2(\sqrt{3}+1)^2}{2}
=\frac{\sqrt{3}-1+4\sqrt{3}+8}{2}
=\frac{5\sqrt{3}+7}{2}
=\frac{5}{2}\sqrt{3}+\frac{7}{2}

Which is far more correct...
 
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
