`(cos 0^(@)+sin 30^(@)+sin 45^(@))(sin 90^(@)+cos 60^(@)-cos 45^(@))` का मान =

Choose the correct answer in each of the following questions: (cos0^(@)+sin30^(@) +sin45^(@))(sin 90^(@) + cos60^(@)-cos45^(@))=?

The value of (cos 0^(@) + sin 45^(@) + sin 30^(@)) (sin 90^(@) - cos 45^(@) + cos 60^(@)) is

(cos 60^(@) xx cos 30^(@)+sin 60^(@)xx sin 30^(@))/(2 sin 30^(@) xx cos 0^(@)+ sin 90^(@))=?

When (2 sin 60^(@) cos 30^(@) cosec 45^(@))/(tan 45^(@) cos 60^(@) sin 45^(@)) is simplified , we get

Find the value of the following: (sin90^(@)+cos60^(@)+cos45^(@))xx(sin30^(@)+cos0^(@)-cos45^(@))

The value of (sin 30^@ sin 60^@)/(cos 60^@ cos 30^@)-tan45^@ is : (sin 30^@ sin 60^@)/(cos 60^@ cos 30^@)-tan45^@ का मान है?

Evaluate cos45^(@)cos30^(@)+sin45^(@)sin30^(@) .

Evaluate cos45^(@)cos30^(@)+sin45^(@)sin30^(@) .

sin30 ^ (@) sin ^ (2) (60) ^ (@) + 3cos60 ^ (@) tan45 ^ (@) =
