Need to answer a similar question on this tonight for an assesment, but have no idea how to do it, having only dealt with single term trig equations also without powers. Any help would be appreciated
Thanks

Re: Trig help
Hint: treat it like a quadratic equation. Remember to use the identity
$\displaystyle \sin(180^{\circ}x)=\sin(x)$
to get all valid roots.

Re: Trig help
Thanks for posting, what will i do with the 5.232 if i try to factorise it, seems it would make it quite messy

Re: Trig help
Use the quadratic formula.
