Solve the multipleangle equation Use n as an integer constan
Solve the multiple-angle equation. (Use n as an integer constant, where x = [0, 8) when n = 0.)
sin x/4 = (sqrt 3) / 2
x = _____(smaller value for n = 0)
x = _____ (larger value for n = 0)
Solution
sin(x/4)=-sqrt3/2
taking sine inverse on both sides
x/4=sin-1(-sqrt3/2)
x/4=4pi/3 , 5pi/3
x=16pi/3 , 20pi/3
