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

Q.Determine x if (x sin^(2)30^(@)cos^(2)60^(@))/(4cos^(2)45^(@))=(3sin^(2)45^(@)+2cos^(2)30^(@))/(sin^(2)90^(@)-4cos^(2)45^(@))

Evaluate : ( 2 ( sin^2( 60^(@ )) + cos^2( 60^(@ )))) / ( tan^2( 45^(@ )) - cos^2( 90^(@ )) + sin( 90^(@ ))

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

Find the value of (sin30^(@))/(cos^(2)45^(@))-tan^(2)60^(@)+3cos90^(@)+sin0^(@) .

Evaluate: (sin^(4) 60^(@) + sec^(4)30^(@)) - 2(cos^(2)45^(@) - sin^(2) 90^(@))

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

Find the value of 4(sin^(4)30^(@)+cos^(4)30^(@))-3(cos^(2)45^(@)+sin^(2)90^(@)) .

Evaluate: sin^(2)60^(@) cos^(2)45^(@) cos^(2)60^(@)" cosec"^(2)90^(@)

Evaluate: (sin^(4) 60^(@) + sec^(4) 30^(@)) - 2 (cos^(2) 45^(@) - sin^(2) 90^(@))
