" (i) "sin^(2)6^(@)+sin^(2)12^(@)+sin^(2)18^(@)*+...+sin^(2)84^(@)+sin^(2)90^(@)=8

What is the value of the sin^(2) 6^(@) + sin^(2) 12^(@) + sin^(2) 18^(@) + "……" + sin^(2) 84^(@) + sin^(2) 90^(@) ?

sin^(2)5^(@)+sin^(2)10^(@)+sin^(2)15^(@)+ .....+sin^(2)85^(@)+sin^(2)90^(@) is equal to

Show that sin^(2) 12^(@)+ sin ^(2)21^(@)+ sin ^(2)39^(@)+ sin^(2)48^(@)=1+ sin^(2)9^(@)+ sin^(2)18^(@)

sin^(2)5^@+sin^(2)10^@+sin^(2)15^@ +.......+sin^(2)85^@ + sin^(2)90^@=

Find the value of sin^(2)1^(@)+sin^(2)2^(@)+sin^(2)3^(@)+ ----+sin^(2)87^(@)+sin^(2)88^(@)+sin^(2)89^(@)+sin^(2)90^(@) .

The value of sin^(2) 1^(@) + sin^(2) 2^(@) + sin^(2) 3^(@)+ . . . . + sin^(2) 89^(@) + sin ^(2) 90^(@) is

The value of sin ^(2) 12 ^(@) + sin ^(2) 12 ^(@) + sin ^(2) 39^(@) + sin ^(2) 48^(@) - sin ^(2) 9^(@) - sin ^(2) 18^(@) is "______"

Prove that: sin^(2)12^(@)+sin^(2)21^(@)+sin^(2)39^(@)+sin^(2)48^(@)=1+sin^(2)9^(@)+sin^(2)18^(@)
