(i) sin10^(@)sin50^(@)sin70^(@)

sin50^(@)-sin70^(@)+sin10^(@)=?

Find 1-sin10^(@)sin50^(@)sin70^(@) .

sin 10 ^(@) sin 50^(@) sin 70^(@) = (1)/(8).

Prove the following: (i) "sin" 10^(@) sin 50^(@) sin 70^(@)=(1)/(8) (ii) "sin" 10^(@) sin 30^(@) sin 50^(@) sin 70^(@)=(1)/(16)

Prove that: sin10^(0)sin30^(0)sin50^(@)sin70^(@)=(1)/(16)

Prove : sin 10^(@)sin50^(@)sin70^(@) = 1//8 .

(cos20^(@)+8sin10^(@)sin50^(@)sin70^(@))/(sin^(2)80^(@))=

sin10^(@)sin50^(@)sin60^(@)sin70^(@)=(sqrt(3))/(16)
