sin60^(@)+cos60^(@)

Find the value of sin60^(@)cos30^(@)+cos60^(@)sin30^(@) .

Prove that : sin60^(@)cos30^(@)+cos60^(@).sin30^(@)=1

Find the value of sin60^(@)cos30^(@)+cos60^(@)sin30^(@) .

Values of trigonometric ratios at 0:30:45:60 and 90.(i)sin30^(@)*cos60^(@)+sin60^(0)*cos30^(@)

Find the value of (tan60^(@))/(sin30^(@)+cos60^(@))

Find the value of (tan60^(@))/(sin30^(@)+cos60^(@))

Evaluate : (i) sin60^(@)*cos30^(@)-cos60^(@)*sin30^(@) (ii) tan30^(@)*cosec60^(@)+tan60^(@)*sec30^(@) .

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^(@)

If xtan45^(@).cos60^(@)=sin60^(@)cot60^(@) , then x is equal to
