    points of intersection

    y=x^3-2x+1

    y=x^2
    The question says to use the bisection method to find the points of intersection of the 2 curves. I know how to use the bisection method to find the root of an equation (like on this page First Steps in Numerical Analysis), but how would I use it to find the point of intersection? Thanks.

    You have y=x^3-2x+1 and y=x^2 and intersection occurs at x^2=x^3-2x+1

    Holding that thought

    x^2=x^3-2x+1

    x^2-x^3+2x-1= 0

    Now apply the bisection method, to kick if off try the interval (0,1)
