Question

Any body good at solving 1/2 angle questions

thetha=480
Find: sin1/2thetha
cos1/2thetha
tan1/2thetha

Answer 1

\[\theta = 480 \]
\[\sin \frac{ \theta }{ 2 }= \sin \frac{ 480 }{ 2} = \sin 240\]

Answer 2

cos 240 =
tan 240 =

Answer 3

uhm so the answer would be for sin -rad3/2
cos1/2 =-1/2
tan1/2= rad 3

Answer 4

sin 240deg = -0.86602540378
