Solve sinx + sin(x/2) = 0 for x between 0° and 360°

Hi.

Could someone please help me with the following question? I would really appreciate any help as I am completely stuck at the moment.

Solve sinx + sin(x/2) = 0 when x is between (and including) 0 and 360 degrees.

Thank you.

Hey Cathy,

Try writing;

[tex]\sin(x) = -\sin(x/2)[/tex]

[tex]\sin(x) = \sin(-x/2)[/tex]

Solve sinx + sin(x/2) = 0 for x between 0° and 360°
