Sin(x)+sin(x/2)=0 Solve the equation for 0'<=x<=360'

'= degrees
pease explain how to do this

x+x/2=90
2x +x = 180
3x = 180
x=60

Well if you are graphing (360 = 2pi) then it should be just a normal sine graph that is shifted to the left by sin(x/2)

=Sin(1/2)x
=45'
So.. 360/45 = 1/8

Therefore the graph is shifted left 1/8pi
