Question

Evaluate : (sin 90^o/cos 45^o) + (1/cosec 30^o)

Answer 1

(1/1/√2) + (1/2)

√2 + 1/2

(2√2+1)/2

Answer 2

Here is your answer....

= ( sin90°/cos45° ) + ( 1/ cosec 30°)

sin 90° = 1

cos 45° = 1/√2

cosec 30° = 2

Now putting this values in the given equation..
we get,

$= \frac{1}{ \frac{1}{ \sqrt{2} } } + \frac{1}{2} \\ \\ = \sqrt{2} + \frac{1}{2}$
Hope this helps you....✌✌
