Question

\[\sin \Pi/6*\sin 2\Pi/6*\sin 4\Pi/6*\sin 5\Pi/6\] is ?

Answer 1

180/6 = 30 ... I think they all have standard values at the multiples of 30??

Answer 2

and finish your other problem first ...

Answer 3

The answer is 3/16

Answer 4

@experimentX

Answer 5

Jeez ...
sin(pi - x) = sin(x)
use the property for 5x and 4x ... they all have standard values ... put those and get your answer

Answer 6

@FoolForMath plzzz help

Answer 7

what have you tried so far ...?

Answer 8

yes not getting

Answer 9

i did nt understand ur way

Answer 10

@ParthKohli help

Answer 11

sin(30)=??
sin(60)=??
sin(120) = ?
sin(150) = ??

Answer 12

if you have difficult evaluating 150 or 120
sin(150) = sin(180 - 150) = sin(30)
similarly sin(120) = sin(60)

you know these standard values ... if you don't know ... check google for trigonometric table ...
and \( \pi \) = 180 degre
