Im working on a part off my course and it covers this, but its not clear.
[tex]\phi[/tex]= half (1+[tex]\sqrt{5}[/tex])
[tex]\varphi[/tex]=half (1-[tex]\sqrt{5}[/tex])The question asks [tex]\phi[/tex]-[tex]\varphi[/tex] =[tex]\sqrt{5}[/tex]
It is written in my book, the answer but it does not explain how the maths cancels and manipilates.
Could you show me a way that the answer is derived.
