Question

find the value of cosec^2 60 - sec^2 60

Answer 1

Answer:

Correct option is

B

cot260∘

cosec260°−1=(32)2−1=34−1=31

Now, (A)cos260°=31

⇒     (B)cot260°=(31)2=31

∴cosec260°−1=cot260°

Answer 2

Answer:

answer = -8/3

Step-by-step explanation:

cosec^2 60- sec^ 60

(2/$\sqrt{3$)^2 - (2)^2

4/3 - 4

4/3 - 12/3

-8/3
