How do you find these on the unit circle: 5pi/2 ? howabout pi/8 ? Converting from polar to rectangular?
It says convert (-1, pi/8 ) from polar to rectangular coordinate? But there is no pi/8 on the unit circle?
If the'yre on the unit circle just use x=rcosθ and y=rcosθ
another example is for (1, 5pi/2) That doesn't seem to be on the unit circle either. So how can we do these then?
