=> cosec-1110
=> -cosec 1110
=> -cosec(90x13 - 60°)
Since 90° is multiplied with an odd number. it will change to sec
=> - sec 60°
But it will be positive as it lies in first quadrant.
=> 2
=> -cosec 1110
=> -cosec(90x13 - 60°)

We have , cosec(-1110)
.) Now we have to find the value of cosec(-1110)
cosec(-1110) = -cosec(1110)
= -cosec( 90*12 + 30)
= -cosec(3*360 + 30) ( function lies on the first quadrant )
= -cosec(30)
= -2
