(cot30^(@))/(sin60^(@)+cos60^(@))

"(1) "sin60^(@)cos30^(@)+sin30^(@)cos60^(@)

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

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

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

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

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

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

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

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