3sin^(2)30^(@)+2cos^(2)45^(@)+3tan^(2)60^(@)=

Evaluate each of the following :- 2sin^(2)30^(@)-3cos^(2)45^(@)+tan^(2)60^(@)

Find the value of the following: (i) "sin"^(2)30^(@)+"sin"^(2)45^(@)+"sin"^(2)60^(@)+"sin"^(2)90^(@) (ii) 2"sin"^(2)30^(@)-3cos^(2)45^(@)+cos^(2)60^(@)

Prove that : (4)/(3) tan ^(2) 30^(@) + sin ^(2) 60^(@) - 3 cos ^(2) 60^(@) + (3)/(4) tan^(2) 60^(@) - 2 tan^(2) 45^(@) = (25)/(36)

sin^(2) 60^(@) + 2 tan 45^(@) - cos^(2) 30^(@)

The value of sin^(2)30^(@).cos^(2)45^(@)+2tan^(2)30^(@)-sec^(2)60^(@) is equal to :

Find the value of (4sin^(2)60^(@)-cos^(2)45^(@))/(tan^(2)30^(@)+sin^(2)0^(@))

Find the value of sin^(3)60^(@) cot 30^(@)-2 sec^(2) 45^(@)+3 cos60^(@) tan45^(@)-tan^(2)60^(@) .
