Find the value of, (4)/(3)cot^(2)30^(@)+3sin^(2)60^(@)-2" cosec"^(2)60^(@)-(3)/(4)tan^(2)30^(@) :

Calculate : (4)/(3)cot^(2)30^(@)+3 sin^(2) 60^(@)-2 "cosec"^(2)60^(@)-(3)/(4) tan^(2)30^(@) .

Prove that (4)/(3)cot^(2)30^(@)+3sin^(2)60^(@)-2" cosec"^(2)60^(@)-(3)/(4)tan^(2)30^(@)=3(1)/(3) .

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)

cos^(2)0^@-2cot^(2)30^(@)+3cosec^(2)90^(@)=2(sec^(2)45^(@)-tan^(2)60)

Evaluate : 4(sin^(4)30^(0)+cos^(4)60^(@))-(2)/(3)(sin^(2)60^(@)-cos^(2)45^(@))+(1)/(2)tan^(2)60^(@)
