Question

Prove that
(cosec - sec) (cot - tan) = (cosec+sec) (sec×cosec + 2)
​

Answer 1

Answer:

The answer is 8√2

Step-by-step explanation:

taking value of thita as 45 degree:-

(cosec - sec)( cot -tan)=LHS

and ( cosec + sec) ( sec × ( cosec +2)

(√2-√2)(1-1)=(√2+√2)√2×√2+2)

0=. 2√2 × 4

which gives 8√2
