Question

Find the exact value.

1/2cos pi/12+sqrt(3)/2 sin pi/12

Answer 1

looks like the addition angle formula for sine

Answer 2

\[\frac{ 1 }{ 2 }\cos \frac{ \pi }{ 12 }+\frac{ \sqrt{3} }{ 2 }\sin \frac{ \pi }{ 12 }\]

Answer 3

\[\sin(\frac{\pi}{3})\cos(\frac{\pi}{12})+\cos(\frac{\pi}{3})\sin(\frac{\pi}{12})\]

Answer 4

no that was wrong sorry

Answer 5

\[\sin(\frac{\pi}{6})\cos(\frac{\pi}{12})+\cos(\frac{\pi}{6})\sin(\frac{\pi}{12})\]

Answer 6

that looks better i think

Answer 7

addition angle formula for sine

Answer 8
