Asked by Dylan
ok I appologize for my stupidity...
I'll answer your question...
ok instructions to this problem
In problems 77-88, use properties of the trigonmetric functions to find the exact value of each expression. Do not use a calculator
85. sin(-pi/12)csc( (25 pi)/12 )
book dosen't say weather or not if it's in radians but I assume it is...
Ok I just put it into my calculator and got negative one I'm in radian mode...
Here's what I put in my calculator...
(sin(-pi/12))/(sin((25pi)/12))
My back of the book, sense this is an odd problem gives me also -1 here's why...
when you added pi to the denomenator you forgot to make it negative...
this would give you negative one
ok
I have a question
why is sin(-20)/cos 380
= to tan of -200
I know sin over cos is tan just don't see were the -200 came from thanks!

see...
(- sin pi/12 + pi)/(sin (25 pi)/12 + pi)
this becomes
(sin pi/12 + pi)/(-sin (25 pi)/12 + pi)
finish it off and you get negative one...
why is sin(-20)/cos(380) equal to tan(-200)
I don't understand
(- sin pi/12 + pi)/(sin (25 pi)/12 + pi)
this becomes
(sin pi/12 + pi)/(-sin (25 pi)/12 + pi)
finish it off and you get negative one...
why is sin(-20)/cos(380) equal to tan(-200)
I don't understand
