Challenge Question



















































































































































































































































In the diagram above we have a circle of radius 1 centered at (0, 0). A straight line is drawn
from the "North Pole" (0, 1)



to the point ( 2, 0 ) on the x axis. The line meets the circle at ( x, y ). Where is ( x, y ) ?





















x =


y =




























If instead of using ( 2, 0 ) we use ( a, 0 ), can you find a formula for ( x, y
) in terms of a ?
