Question:

Find the value of (1+sec22° + cot68°)(1-cosec22° + tan68°)

Options:

0

-1

1

2

Correct Answer:

2

Explanation:

If in expression sum of angles is 90° then

Put every θ = 45° or anything

(1+sec22° + cost68°)(1-cosec22° + tan68°) = (1+\(\sqrt {2}\)+1)(1-\(\sqrt {2}\)+1)

(2)2 - (\(\sqrt {2}\))2 = 2
