Answer 1

Answer:

-1/2

Step-by-step explanation:

hope it helps you all the best

Answer 2

Step-by-step explanation:

cosec square 30 degree=4

because ( cosec 30 degree =2)

sin square 45 degree=1/2

because (sin 45 degree =1/root2 )

sec square 60 degree=4

because ( sec 60 degree =2 )

so

cosec square 30degree - sin square 45 degree - sec square 60 degree

=4-1/2-4

=-1/2
