(cos30+sin60)/(1+cos60+sin30)=(sqrt(3))/(2)

Prove that: (cos30^0+sin60^0)/(1+cos60^0+sin30^0)=(sqrt(3))/2

Prove that: (cos30^(@)+sin60^(0))/(1+cos60^(@)+sin30^(@))=(sqrt(3))/(2)

Evaluate: (cos 30+sin 60)/(1+cos 30+sin 60)

Verify:d. (cos30^@-sin30^@)/(cos30^@+sin30^@)=sec60^@-tan60^@

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?

Show that : (i) (1-sin60^(@))/(cos60^(@))=(tan60^(@)-1)/(tan60^(@)+1) (ii) (cos30^(@)+sin60^(@))/(1+sin30^(@)+cos60^(@))=cos30^(@)

cos30^(@)sin60^(@)+cos60^(@)sin30^(@)= ……………………

sin60^@cos30^@ + cos60^@ sin30^@ is equal to (A) frac(3)(2) (B) frac(5)(2) (C ) 1 (D) 2

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^(@)
