मान निकालें : `sin30^(@)cos45^(@)+cos30^(@)sin45^(@)`

Evaluate each of the following : sin30^(@)cos45^(@)+cos30^(@)sin45^(@)

If tan x =sin 45^(@) cos 45^(@) cos 45^(@)+Sin30^(@) ,then x is equal to:

Verify each of the following : (i) sin60^(@)cos30^(@)-cos60^(@)sin30^(@)=sin30^(@) (ii) cos60^(@)cos30^(@)+sin60^(@)sin30^(@)=cos30^(@) (iii) 2sin 30^(@)cos30^(@)=sin60^(@) (iv) 2sin45^(@)cos45^(@)=sin90^(@)

Evaluate sin45^(@)+cos45^(@)

(sin30^(@)cos45^(@))/(tan 60^(@)) is equal to

The value of sin^(2) 60^(@)+cos^(2)30^(@)-sin^(2)45^(@) is _________

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

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

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