The value of the expression Cosec(85ᵒ + θ) - Sec(5ᵒ - θ)…

The value of the expression Cosec(85^o + θ) - Sec(5^o - θ) - tan(55^o + θ) + Cot(35^o - θ) is:

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e 0

Explanation:

Cosec(85^o + θ) - Sec(5^o - θ) - tan(55^o + θ) + Cot(35^o - θ)

= Cosec(85^o + θ) - Sec(90 - (85^o + θ)) - tan(55^o + θ) + Cot(90 - (55^o + θ))

= Cosec(85^o + θ) - Cosec(85^o + θ) - tan(55^o + θ) + tan(55^o + θ)

= 0
