sin^(2)(51^(@)-x)+sin^(2)(39^(@)+x)=

The value of sin^(2)51^(@)+sin^(2)39^(@) is

sin ^ (2) (51 ^ (0) -x) + sin ^ (2) (39 ^ (@) + x) = 1) -12) 03) 14) 2

If cosec39^(@)=x , then the value of (1)/(cosec^(2)51^(@))+sin^(2)39^(@)+tan^(2)51^(@)-(1)/(sin^(2)51^(@)sec^(2)39^(@)) is.

If sin ^(2) x + (1)/(4) sin^(2) 3x = sin x sin^(2) 3 x then x =

Solve (sin^(2) 2x+4 sin^(4) x-4 sin^(2) x cos^(2) x)/(4-sin^(2) 2x-4 sin^(2) x)=1/9 .

Solev (sin^(2) 2x+4 sin^(4) x-4 sin^(2) x cos^(2) x)/(4-sin^(2) 2x-4 sin^(2) x)=1/9 .

The value of (sin24^(@)cos6^(@)-sin6^(@)sin66^(@))/(sin21^(@)cos39^(@)-cos51^(@)sin69^(@)) is

Value of (2sin9^(@)sin 21^(@)sin 39^(@)sin 51^(@)cos21^(@)sin 81^(@))/(sin54^(@)) is equal to:-

Value of (2sin9^(@)sin 21^(@)sin 39^(@)sin 51^(@)cos21^(@)sin 81^(@))/(sin54^(@)) is equal to:-
