(A) The given expression is a product of cosine values from $1^\circ$ to $179^\circ$.We know that the sequence of angles includes $90^\circ$.Since $\cos 90^\circ = 0$,the entire product becomes zero because any number multiplied by zero is zero.Therefore,$\cos 1^\circ \cdot \cos 2^\circ \cdot \cos 3^\circ \dots \cos 90^\circ \dots \cos 179^\circ = 0$.

$\cos 1^\circ \cdot \cos 2^\circ \cdot \cos 3^\circ \dots \cos 179^\circ = $
