cos 1° cos 2° cos 3° ....... cos 179° cos 180°.

= cos 1° cos 2° cos 3° .......cos 89° cos 90° cos 91°……..  cos 179° cos 180°.

= cos 1° cos 2° cos 3° ...... cos 89° (0) cos 91°……..  cos 179° cos 180°.

[cos 90° = 0]

= 0

Hence, the value of cos 1° cos 2° cos 3° ....... cos 179° cos 180° is zero (0) .
