Use the bisection method or a graphing calculator to find the coordinates of the two points on the graph of that lie r = 1 unit from the origin. Give the result to the nearest hundredth, I just need a direction to go on this problem
There are infinite points that lie on the r=1 circle.
Use trial and error, start with a value of x (<1) and adjust y so that the distance √(x²+y²)=1.
For example, try x=0.5,
Try a bigger y,
try a bigger y...
