good evening everyone.. ^^
just wanna ask for your help with this trigonometric equation...
1 - [ sin (x) - cos ^ 2 (x) ] / sin (x) = 2 cos (x)..
how would i prove it????
..please help me...
thanks... thanks... thanks...
sorry for the late response...
that's the question written in our textbook...
i just dunno if there's any typographical error..
but if there is..
then the equation must be..
1 - ( sin x - 2 cos x)
__________________ = 2 cos x..
how about that???
if this is also wrong.. then i think.. we can't do anything more about it..
anyway.. thank you so much for your help.. ^^
I am just trying to improve my skills by trying out more questions, so don't feel too bad about it, instead, you have helped me! I would gain knowledge when an expert gets in to solve this question
By the way, as I am no expert in trigonometry, don't assume anything about the question yet... The question may be set correctly but haven't found someone to conquer it yet.
