Question

Help please....Use a Double- or Half-Angle Formula to solve the equation in the interval [0, 2π). (Enter your answers as a comma-separated list. Round your answers to three decimal places where appropriate.)
sin 2θ + sin θ = 0

Answer 1

start with
\[2\sin(x)\cos(x)+\sin(x)=0\] then factor as
\[\sin(x)(2\cos(x)+1)=0\] and finally set
\[\sin(x)=0\] and solve for \(x\), also \[2\cos(x)+1=0\] and solve for \(x\)
