Question

The value of the expression [cosec (75° + theta) - sec (15° - theta) – tan (55° + theta) + cot (35° - theta)] is
(A)- 1
(B) 0
(C) 1
(D)3/2
​

Answer 1

Answer:

(C) 1

Step-by-step explanation:

I am not sure

but this is my answer

Answer 2

answer:

the answer is "0"

explanation:

$\cos( \sec(75 + 0) ) - \: \sec(15 - 0)$

$- \tan(55 + 0) + \cot(35 - 0)$

$\cos( \sec(75 + 0) ) - \: \sec \\ (90 + (15 - 0) - \tan(55 + 0) + \\ \cot(35 - 0)$

$hence \: = 0$
