Question

The value of sin1° sin2° sin3°...sin180°...sin196° is:

A.

14\frac{1}{4}​​

B.

12\frac{1}{2}​​

C.

0

D.

13\frac{1}{3}​​

Correct option is C

Given:

sin(1)×sin(2)×sin(3)××sin(180)××sin(196)\sin(1^\circ) \times \sin(2^\circ) \times \sin(3^\circ) \times \dots \times \sin(180^\circ) \times \dots \times \sin(196^\circ)​​

Solution:
In this product, we have sin(180),\sin(180^\circ),​ and we know that:

sin(180)=0\sin(180^\circ) = 0

Since one of the terms in the product is zero, the entire product becomes zero.
