Hi,
There are 360 degrees in a circe, right? So going around a circle 300 degrees one way, is the same as going 60 degrees the other way. So sin(300)=sin(-60). Now you should know that sin(-x)=-sin(x). So we are down to sin(300)=-sin(60). You should also know that sin(60)=
so the answer is:
=-\frac{\sqrt{3}}{2})
Hope that helps,
Kev
