" (vii) "(4(sin^(2)60^(@)-cos^(2)45^(@)))/(tan^(2)30^(@)+cos^(2)90^(@))

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

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

Evaluate the following : (5cos^(2)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

(5cos^(6)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

Evaluate the following: (v) (5cos^(2)60^(@)+4 sec^(2) 30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

The value of (cos^(2)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@)) is

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^(@)

Calculate : (1-sin^(2)30^(@))/(1+sin^(2)30^(@))xx(cos^(2)60^(@)+cos^(2)30^(@))/("cosec"^(2)90^(@)-cot^(2)90^(@)) divide (sin60^(@) tan30^(@))
