Question
im having trouble finding a general solution for sin2x+sinx=0
all of the examples our teacher gave in class seem much different and i'm not sure what to do. i tried to start by using the sum-to-product formula but now i'm stuck. any suggestions?

Isn't sin2x= sinx cosx?
sinx(cosx+1)=0
sinx(cosx+1)=0

sin2x=2sinx cosx
sinx(2cosx+1)=0
sorry aboutthat .
sinx(2cosx+1)=0
