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:



Hope that helps,
