The value of sin^(2)15^(@)+sin^(2)25^(@)+sin^(2)65^(@)+sin^(2)75^(@) is

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

Find the value of sin^(2)5^(@)+sin^(2)10^(@)+sin^(2)15^(@)+.............+sin^(2)90^(@) .

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

Find the value of sin^(2) 45^(@) - sin^(2) 15^(@)

What is the value of sin^(2) 15^(@) + sin^(2) 20^(@) + sin^(2)25^(@) + ……… + sin^(2) 75^(@) ?

Prove that sin^(2)5^(@) +sin^(2)10^(@) + sin^(2)15^(@)+...+sin^(2)90^(@)=(19)/(2)

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