4. The "bi-secant method" is a combination of the secant method and the bisection method.
As in the case of the secant method, it uses two points (a, f(a)), (b, f(b)) to find a secant line
that goes through those points and computes a point c where the secant intersects the r axis.
As in the case of the bisection method, we require that f(a)f(b) < 0, and assuming that
a <c<b the method uses sign change to determine in which side of c the solution is.
(a) Find the equation of the secant line line between the points (a, f(a)) and (b, f(b))
Hint: It helps to visualize this method graphically (draw the points and the line)
(b) Find a point c where the secant line between the points (a, f(a)) and (b, f(b)) intersects
the x-axis

(c) Notice that if there is a sign change in the function from a to c then the solution is in [a, c]
otherwise, the solution is in [c, b]
Use the description above, and your formula for c to write the bi-secant algorithm
such that that given f(r), a, b, e, N returns an approximation to the solution of f(r) with
error tolerance e, or an error, if the number of iterations exceeds N
