Question

cot 30° . cosec 90° + din 60° . cosec 30°​

Answer 1

Answer:

= $2 \sqrt {3}$

Step-by-step explanation:

cot 30° . cosec 90° + sin 60° . cosec 30°​

=> cot 30° = $\sqrt {3}$

=> cosec 90° = 1

=> sin 60° =  $\sqrt {3}$ / 2

=> cosec 30° = 2

so,

$\sqrt {3}$ x 1 +   $\sqrt {3}$ / 2 x 2

$\sqrt {3}$ + $\sqrt {3}$

= $2 \sqrt {3}$
