Given : Cosec(-7498)

To find : To be expressed as   function of angle less than 45 degree

Solution:

Cosec(-7498)

adding subtracting 360 deg does not effect

=>  Cosec(-7498) = Cosec (-7498° + 360°*20)

=> Cosec(-7498) = Cosec (-7498° + 7200°)

=> Cosec(-7498) = Cosec (-298°)

=> Cosec(-7498) = Cosec (-298° + 360°)

=> Cosec(-7498) = Cosec (62°)

Cosec x = Sec (90° - x)

=>  Cosec(-7498) =  Sec(90° - 62°)

=>  Cosec(-7498) =  Sec(28°)

Sec(28°)    =  Cosec(-7498)
