Solution:-
Here,
RHS = 3/16
so,
LHS:-
=sin 20 × sin 40 × sin 60 × sin 80
=0.34 × 0.64 × 0.86 × 0.98
=0.194
Now,
RHS:-
3/16 = 0.1875
From this LHS and RHS are little bit same. So if you will do it accurately then it will be same.
So, I can say that
sin 20. sin40.sin 60. sin 80 = 3/16
Here,
RHS = 3/16
so,
LHS:-
=sin 20 × sin 40 × sin 60 × sin 80
=0.34 × 0.64 × 0.86 × 0.98
=0.194
Now,
RHS:-
3/16 = 0.1875
From this LHS and RHS are little bit same. So if you will do it accurately then it will be same.
So, I can say that
sin 20. sin40.sin 60. sin 80 = 3/16
