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

What is the value of (tan^4 60^@-sin^4 90^@ ) - 2(tan^2 45^@ +3 cos ^2 0^@)

Prove that 2 (sin ^ (6) A + cos ^ (6) A) -3 (sin ^ (4) A + cos ^ (4) A) + 1 = 0

2(sin^(6) theta + cos^(6)theta) - 3(sin^(4)theta + cos^(4)theta)+ 1 = 0

(tan) (11 pi) / (3) (- 2sin) (4 pi) / (6) - (3) / (4) (cos ec ^ (2)) (pi) / (4) + (4cos ^ (2)) (17 pi) / (6) = (3-4sqrt (3)) / (2)

sin ^ (2) ((2 pi) / (3)) + cos ^ (2) ((5 pi) / (6)) - tan ^ (2) ((3 pi) / (4))

Evaluate : [{:(,4 sin 30^@ 2 cos 60^@), (,sin 90^@ 2 cos 0^@):}] [{:(,4,5),(,5,4):}]
