Here's my work:
sin(x) + sin(2x) = 0
what do I do now? I can't think of any trig identities or anything to simplify it? Do i just do sin(x) = - sin(2x) which obviously isn't true, does anyone know??
Sorry about that, the picture is solve for sin(x) + 2*sin(x)*cos(x) = 0 for 0 degrees <= x < 180 degrees
I used a double angle idendtity to reduce from the aforementioned equation to sin(x) + sin(2x) = 0
