Evaluate : `(cos 45^(@))/(sec30^(@)+"cosec "30^(@))`

Evaluate (cos 45^(@))/(sec 30^(@) + cos 30^(@))

What is the value of (sin 45^(@))/(sec 30^(@)+ "cosec" 30^(@))?

What is the value of (sin 45^@)/(sec30^@ + cosec 30^@) ?

Evaulate : (tan45^(@))/("cosec "30^(@))+(sec60^(@))/(cot45^(@))-(2sin90^(@))/(cos0^(@)) .

The value of 2tan 45^(@)- sec 60^(@)+ cosec 30^(@) is

sec 30^@ + cos 30^@ = ?

Evaluate : ( 5 cos ^(2) 60^(@) + 4 sec ^(2) 30^(@) - tan ^(2) 45^(@))/( sin ^(2) 30^(@) + cos ^(2) 30^(@))
