Hi. I can't understand what this problem is asking. Here it is:
"Find the complete solution (to the nearest tenth) if sin(theta) = -98544973 and 0 </= theta < 2pi."
The answer is 4.5 and 4.9 it says.
I know that arcsin(-98544973) = -80.214 degrees = 279.8 degs.
I know that -98544973 is the length of the opposite leg to the reference angle in the unit circle for sine below the x-axis.
So, where does 4.5 and 4.9 come from? Stumped
