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

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)

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^(@) .

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

4sin^(2)60^(@)+3tan^(2)30^(@)-8sin45^(@)*cos45^(@)

(4(sin^(2)60^(@)+cos^(2)60^(@)))/(tan^(2)45^(@)-cos^(2)90^(@)+sin90^(@))

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

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

(kcosec^(2)30^(@).sec^(2)45)/(8cos^(2)45^(@).sin^(2)60^(@))=tan^(2)60^(@)-tan^(2)30^(@) , then k = ?
