Best ResponseYou've already chosen the best response.0to make it easy add 2pi into 12pi ntill you get positive value and remember sec =1/cos

Best ResponseYou've already chosen the best response.0add 2pi \[\huge\rm 12\pi +2\pi\] full circle is equal to 2pi that's why we have to add 2pi keep adding 2 untill u get positive number

Best ResponseYou've already chosen the best response.0\[12\pi +2\pi = 10 \] still negative add 2pi again \[10\pi +2\pi = 8\pi \] add 2pi again

Best ResponseYou've already chosen the best response.0so it is not an exact value then

Best ResponseYou've already chosen the best response.0\[12\pi +2\pi = 10 \] still negative add 2pi again \[10\pi +2\pi = 8\pi \] add 2pi again \[8\pi +2\pi = 6\pi \] add 2pi \[6\pi +2\pi = 4\pi \] \[4\pi +2\pi = 2\pi \] add 2 pi again and let me know what you get

Best ResponseYou've already chosen the best response.0like i told you sec =1/cos look at the unit cricle what is cos at 0

Best ResponseYou've already chosen the best response.0yep right so \[\huge\rm sec =\frac{1}{cos} =sec =\frac{ 1 }{ 1 }\] replace cos by 1 = answer

Best ResponseYou've already chosen the best response.0if the answer is 0 the is it undefined or not

Best ResponseYou've already chosen the best response.0they are asking for value of sec(12pi) in the unit circle radians is 0 to 2pi(12pi is not in the unit circle t decrease the value we added 2pi ) degree 0 to 360

Best ResponseYou've already chosen the best response.0so in other words question is find the value fo sec(0)

Best ResponseYou've already chosen the best response.0sec(0) is same as sec(12pi) both are equal

Best ResponseYou've already chosen the best response.0no i am just asking in general, does the answer 0 mean undefined

Best ResponseYou've already chosen the best response.0ohh okay no well if the DENOMINATOR is 0 then YES!! answer is undefined

Best ResponseYou've already chosen the best response.0okay here is an example let's say they are asking csc(0) and csc equal to 1/sin and now sin (0) is 0 right

Best ResponseYou've already chosen the best response.0so when you replace sin by 0 your answer would be undefined because there is a zero at the denominator \[\large \rm csc = \frac{ 1}{\sin} = \frac{ 1 }{ 0 }=\rm undefined\]

Best ResponseYou've already chosen the best response.0\[\huge\rm \frac{ 1 }{ 0 }= undefined ~~~~~~~~~~~~~\frac{ 0 }{ 1}=1\] and just simple 0 doesn't mean undefined
