Question

Evalute: sin (10°) × sin (30°) × sin (80°) × sin (60°) × sin(0°)​

Answer 1

Answer:

We have,

sin (10°). sin (30°) - sin (80°) - sin (60°) - sin (0°)

To find, the value of sin (10°). sin (30°) - sin (80°) - sin (60°) - sin (0°) = ?

∴ sin (10°). sin (30°) - sin (80°) - sin (60°) - sin (0°)

= sin (10°). () - sin (80°) -

- 0

[ ∵ sin 30° = , sin 60° =

, sin 0° = 0]

= sin (10°). () - sin (80°) -

Hence, sin (10°). sin (30°) - sin (80°) - sin (60°) - sin (0°) is sin (10°). () - sin (80°) -

.

Answer 2

Answer:sin(10°)×(sin30°)×sin(80°)

×sin(60°)×sin0°

sin(10°)×(sin30°)×sin(80°)×sin(60°)×0

(Value of sin0°=0)

=0

(Any number multiplying by 0. We always get 0 as answer)
