hello, can someone help me with this equation??looked for help at Edit [Moderator]: Links removed but nothing so far..thanks..
tg α = m, (m = √3); π<α<3π/2
find: cos α, cos α/2, cos 2α
If tg means 'tangent' then from tan^-1 root 3
a = 240 degrees (4pi/3)
(root 3 is the 60 degree and 240 degree value but 60 degrees is less than pi)
Go from there.
