32sin^(6)15^(0)-48sin^(4)15^(0)+18sin^(2)15^(0)

32sin^(6)15^(@)-48sin^(4)15^(@)+18sin^(2)15^(@)=

32sin^(6) 15^@ -48 sin^(4) 15 ^(@) + 18 sin^2 15^@ =

sin^(2) 75^(@) - sin^(2)15^(@)=

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)=

Show that sin^(2)5^(@)+sin^(2)10^(0)+sin^(2)15^(0)+...+sin^(2)90^(@)=9(1)/(2)

[sin^(2)5^(0)+sin^(2)10^(0)+sin^(2)15^(0)+...........],[+sin^(2)90^(0)=..........]

What is the value of 2sin15^(@) cos 15^(@)-4sin^(3)15^(@)cos15^(@) ?

The value of (cos ^(6)5^(@)-15 cos ^(4) 5^(@) sin ^(2)5^(@)+15 cos ^(2)5^(@)sin ^(4) 5^(@)-sin ^(6)5^(@)) is equal to-
