Find the value of cos47°sec133° + sin44°cosec136°.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 0.

Given that

The value of cos47°sec133° + sin44°cosec136°

⇒ cos47° sec(180º - 47°) + sin44° cosec(180º - 44°)

⇒ cos47° (- sec47°) + sin44° cosec44° 

⇒  cos47°(-1/ cos47°) + sin44° (1/sin44°)

⇒ -1 + 1

⇒ 0
