Answer 1

\[(1, \frac{ 1 }{ 2 } \pi )\]

Answer 2

\[x=r\cos(\theta), y=r\sin(\theta)\] cmpute
\[x=\cos(\frac{\pi}{2}),y=\sin(\frac{\pi}{2})\]

Answer 3

Answer 5

Well the angle is measured counter clockwise from the right, or EAST direction. So \[\pi/2\] radians is 90 degrees. If you go 90 degrees counter clockwise from the right which one (x or y) will be 1 and which will be 0 ?

Answer 6

(0,1)?
