Find the value of cos 0° + cos 30° - tan 45° + cosec 60° + cot 90°.

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e  723\frac{7}{2\sqrt 3}.

Given that

the value of cos 0° + cos 30° - tan 45° + cosec 60° + cot 90°.

⇒ cos 0° + cos 30° - tan 45° + cosec 60° + cot 90°

⇒ 1 + √3/2 - 1 + 2/√3 + 0

⇒ √3/2 + 2/√3

⇒ 723\frac{7}{2\sqrt 3}
