I want to solve [itex] y''+y'+y=(sin(x))^2 [/itex] and try to use(adsbygoogle = window.adsbygoogle || []).push({});

[itex] y=Ae^{ix} [/itex] but then when I square it I get [itex] A^2 e^{2ix} [/itex]

I found y' and y'' and solved for A and it didn't work I guess I could use the formula for reducing powers but I would like to try and get around that.
