Dear Balsingh,

factor out a sqrt(2) and the 1/4 and you get
Sin75° = √2/4(1+√3)

factor out a sqrt(2) and the 1/4 and you get
Cos75° = √2/4(√3-1)

the √2/4 goes away
so it''s (1+√3)/(√3-1)
rationalize the denominator by multiplying (1+√3) on the top and bottom
you get (1+√3)^2/2 after simplifying
=√3 +2
