3 - 23sin(x) = 0

OpenStudy (anonymous):

it also says Solve the following trigonometric equation for the interval (0,2].

OpenStudy (anonymous):

anybody out there to help me

OpenStudy (btaylor):

If you simplify, you get sin(x) = 3/23. So, there is some triangle that looks like this:|dw:1385584588832:dw| Using the inverse sine (arcsine), we find that x = 0.131 rad = 7.5 degrees. This could also occur in the 2nd quadrant, so 180-7.5 = 172.5 degrees or 1.44 radians.

OpenStudy (anonymous):

no

OpenStudy (anonymous):

my answer choose are 4 ; 3 4 B. 3 ; 2 3 C. 6 ; 11 6 D. 3 ;

OpenStudy (anonymous):

I mean are pie over 4 and 3pie/4 that's a

OpenStudy (anonymous):

b says pie/3 and 2pie/3

OpenStudy (anonymous):

next one says pie/6 and 11pie/6

OpenStudy (anonymous):

last one pie/3 and pie/6

OpenStudy (btaylor):

are you sure it is 3 and 23?

OpenStudy (anonymous):

3 - 23sin(x) = 0 that's the problem

OpenStudy (anonymous):

nun about 23

OpenStudy (btaylor):

hmmmm..... sorry, i don't know what to say.

OpenStudy (anonymous):

did you look at the answer choose

OpenStudy (anonymous):

ill give you a medal please

OpenStudy (anonymous):

helpppppppppppppppppppppppppppppppppppppppppppp somebody

OpenStudy (anonymous):

Solve the following trigonometric equation for the interval (0,2]. 3 - 23sin(x) = 0

OpenStudy (anonymous):

help

OpenStudy (anonymous):

ok the answer is: \[x=2 \pi n+\pi-\sin ^{-1}(\frac{ 3 }{ 23 })\] where; \[n \in \mathbb{Q} \]

OpenStudy (anonymous):

so i think its 2pie/3

OpenStudy (anonymous):

my answer choice are pie/4 and3pie,4 that's a

OpenStudy (anonymous):

anwer chosie b are pie/3 and 2pie/3

OpenStudy (anonymous):

c is pie/6 and 11pie/6

OpenStudy (anonymous):

d is pie/3 pie/6

OpenStudy (anonymous):

so what do think it is
