Evaluate the following : sin60^(@)cos30^(@)+sin30^(@)cos60^(@)

Evalulate the following : sin60^(@)cos30^(@)+sin30^(@)cos 60^(@)

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

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^(@)

Show that (i) cos60^(@)*cos30^(@)-sin60^(@)*sin30^(@)=cos90^(@) (ii) cos60^(@)=1-2sin^(2)30^(@)=2cos^(2)30^(@)-1 (iii) (tan60^(@)-tan30^(@))/(1+tan60^(@)*tan30^(@))=tan30^(@)

cos 60^(@) sin 30^(@) +cos 30^(@) sin 60^(@)=

The valiue of sin60^(@) cos 30^(@) + sin 30^(@)cos 60^(@) is ______.
