just plug the numbers into your favorite calculator. What's the trouble?
or, reduce to
(sin 50)(tan 60) / (cos 180)(tan 50)(sin 40)
= (cos 40)(cot 30) / -(cot 40)(sin 40)
= -cot 30
= -√3
(sin 50)(tan 60) / (cos 180)(tan 50)(sin 40)
= (cos 40)(cot 30) / -(cot 40)(sin 40)
= -cot 30
= -√3
Huh. Strange font messup
that's -√3
that's -√3
sin 130.tan 60/cos 540.tan 230.sin 400
