The value of cosec 30° − cos 60° is:

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 32\frac{3}{2}.

According to the given question, 

cosec 30° = 1sin⁡30∘1 \over \sin 30 ^\circ 

⇒ 1121 \over { 1 \over 2} = 2

cos 60° = ½

Now, cosec 30° − cos 60° = 2 - ½

⇒ 323 \over 2

Hence the required answer is 323 \over 2.
