Answer:
We know,
☆When we multiply any number with zero(0), the answer is always zero (0).
For example,
40 × 0 = 0
(20 + 16 + 1937) × 0 = 0
In the series, cos1°.cos2°.cos3°...............cos100°, cos90° is also included i.e.
=cos1°.cos2°.cos3°...............cos90° cos100°
=cos1°.cos2°.cos3°...............× 0 × cos100°
= 0
So the answer of the given series cos1°.cos2°.cos3°...............cos100°= 0
