sin^(2)(51^(0)-x)+sin^(2)(39^(0)+x)=

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

The value of sin^(2)12^(0)+sin^(2)21^(0)+sin^(2)39^(0)+sin^(2)48^(0)-sin^(2)9^(0)-sin^(2)18^(0)

sin^(2)12^(0)+sin^(2)21^(0)+sin^(2)39^(0)+ sin^(2)48^(2)-sin^(2)9^(0)- sin^(2) 18^(0)=

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

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.
