Ответ:
its the second choice 2 + n< 14
Ответ:
cos(theta) = 1> the value of cos is positive
then
angle theta> could be in the first or fourth quadrant
Part 1) find sin theta
sin² theta+cos² theta=1> sin² theta=1-cos² theta> 1-1²> 0
sin theta=0
Part 2) find csc theta
csc theta=1/sin theta
but sin theta =0
therefore
csc theta> it does not exist, it is not defined
Part 3) find sec theta
sec theta=1/cos theta
cos theta=1
so sec theta=1/1> sec theta=1
Part 4) find cot theta
cot theta=cos theta/sin theta
but sin theta=0
therefore
cot theta> it does not exist, it is not defined
