Prove that:
`sin12^(@)sin48^(@)sin54^(@)=1/8`

Explanation

To prove that \( \sin 12^\circ \sin 48^\circ \sin 54^\circ = \frac{1}{8} \), we will follow these steps:

### Step 1: Rewrite the expression
We start with the left-hand side (LHS):
\[ \sin 12^\circ \sin 48^\circ \sin 54^\circ \]
We can rewrite \( \sin 54^\circ \) using the identity \( \sin(90^\circ - \theta) = \cos \theta \):
