Question 627890: sin pie by 7 multiplied by sin2 pie by 7 multipled by sin3 pie by 7 = root 7 by 8
(prove LHS = RHS ) Answer by Susmitha(21) (Show Source):
You can put this solution on YOUR website! L.H.S.: sin(pi by 7). sin(2pi by 7). sin(3pi by 7)
=(0.4338837391)*(0.7818314825)*(0.9749279122)
=0.3307189139
=root 7 by 8
