Question

Find tha value of cosec 11π/3

Answer 1

Answer:

- 2/$\sqrt{3}$

Step-by-step explanation:

csc (11π/3)

= csc 4π-(π/3)

= - csc (π/3)

= - 2/$\sqrt{3}$

Answer 2

Answer:

-2/root3

Step-by-step explanation:

cosec(11×180)/3

=cosec 660 degree

=cosec (8×90-60) degree

= -cosec60 degree

=2/root3
