Guys my calculator doesn't convert 1.414213562 into root2 when I press the decimal to surd button. It's a Casio fx-83gt plus, any idea how I can fix this? It will convert root2 into 1.414213562 but not the other way round

1.414213562 is not root2

so if you enter the decimal it's just a decimal

if you enter 3.141592654 it won't turn it into pi

if you enter root2 it can show it as an approximate decimal as 1.414213562

Do we need to know how to convert radians into degrees, if so, someone tell me how please?

In your opinion, what is the hardest C2 paper? I wan't to be properly prepared for tomorrow because the Jan 2013 was pretty straight forward.

no you don't

2 pi radians = 360 degress

pi radians = 180 degrees

I don't think there will be a question explicitly asking you do do so but I think that knowledge of the conversion will be pre-assumed!

2pi = 360 degrees

so pi = 180 degrees. And pi is 3.14 something something something. But I don't think you'll have to convert them.

June 2009 or Jan 2010 had the lowest grade boundaries indicating students found them the most challenging

Length of slant as opposed to perpendicular height!

1.414213562 is not root2

so if you enter the decimal it's just a decimal

if you enter 3.141592654 it won't turn it into pi

if you enter root2 it can show it as an approximate decimal as 1.414213562

How would I know that the quadruple root of 4 is plus and minus root2 if it gave me an answer in decimals then for example?
