Question

con(90+theta)sec(-theta)tan(180-theta)/sec360-theta)sin(180+theta)cot(90-theta).​

Answer 1

Answer:

Correct option is C -1

Formulae:

cos(90−θ)=sinθ

sin(90−θ)=cosθ

tan(90−θ)=cotθ

cot(90−θ)=tanθ

sec(90−θ)=cscθ

cosec(90−θ)=secθ

sin(360°+θ)sec(180°+θ)cot(90°−θ)

cos(90°+θ)sec(−θ)tan(180°−θ)

= sinθ.(−secθ)tanθ

−sinθ.secθ(−tanθ)

=−1.

Hence, the answer is −1.
