Question

Find the value of sin 31pi/3.

Answer 1

To find sin 31pi/3 :

= sin{(30pi+ 1pi)/3}

= sin{30pi/3 + pi/3}

= sin(10pi + pi/3)

= sin(pi/3)

= sin 60° =

$\frac{ \sqrt{3} }{2}$

Answer 2

Step-by-step explanation:

Value =

Sin[ 30π + 1π]

Sin 30π+ 1π/3

Sin 10π + π/3

Sin π/3

= Sin 60° = √3/2
