Question

sin 3 pi / 8 evaluate​

Answer 1

Step-by-step explanation:Hey Mate This Might Help You!!!!

sin ( 3\ 8 π ) = 0.9238

Explanation:

sin ( 3 π \8 )

= sin ( 3 π \8 )

We know that  π ^c  (radians) are equal to  180 ° . (If we have a circle where  r = 1

, then the circumference is just  2 π

. If we say the circumference is  360 °

, then  2 π

= 360 °

. Thus,  π =180°  )

Therefore, to evaluate  sin ( 3 π\ 8) , we simply have to replace  π  with  180 .

sin ( 3 π\ 8 )

= sin ( 3 x 180 \8 )

= sin ( 67.5 )

= 0.9238
