Question

(cos^2 ∅ -1)( cosec^2∅)​

Answer 1

Answer:

(cos^2¢-1)(cosec^2¢)

= -(1-cos^2¢)(cosec^2¢)

= -sin^2¢×1/sin^2¢

= -1

Answer 2

Answer:

the answer is 1

Step-by-step explanation:

cos^2 theta -1=sin^2 theta.(1)

cosec^2 theta =1/sin^2 theta.(2)

substitute 1 and 2 in the question

sin^2 theta/ sin^2 theta =1
