`4(sin^(4) 60^(@) + cos^(4) 30^(@))-3(tan^(2) 60^(@) -tan^(2) 45^(@))+ 5 cos^(2) 45^(@)` का मान ज्ञात करो ।

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

4 (sin ^ (4) 60 ^ (@) + cos ^ (4) 30 ^ (@)) - 3 (tan ^ (2) 60 ^ (@) - tan ^ (2) 45 ^ (@)) + 5cos ^ (2) 45 ^ (@)

Show that 2(cos^(4)60^(@)+sin^(4)30^(@))-(tan^(2)60^(@)+cot^(2)45^(@))+3sec^(2)30^(@)=1/4

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

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

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)

(2)/(3)(cos^(4)30^(@)-sin^(4)45^(@))-3(sin^(2)60^(@)-sec^(2)45^(@))+(1)/(4)cot^(2)30^(@)
