$\sin \frac{ \pi }{ 6 } + \cos \frac{ \pi }{ 6}$

$\sin \frac{ \pi }{ 6 } = \frac{ 1 }{ 2 } ~~~~~~ \cos \frac{ \pi }{ 6 } = \frac{ \sqrt{3} }{ 2 }$

oh i think i got it one sec

4. anonymous

(1+sqrt3)/2

umm do you know the standard triangle for 30 degrees and 60 degrees? You may need to use that

6. Astrophysics

Haha I was just going to say, you could make the special triangles

7. UsukiDoll

yeah but someone recked it... by giving values for them -_-

8. Astrophysics

9. Astrophysics

Yeah, that's useless

10. UsukiDoll

giving direct answers is against code of conduct and that guy had to latex it -_-! I know this.. you need to memorize those triangles... it's useful for Calculus and in higher level math.

I love these triangles <3

13. UsukiDoll

but after finding those values, it's correct @Ssaharan
