The secant method for root finding
secant(f, x, tol = 0.001, m = 100)
f |
function to integrate |
x |
an initial estimate of the root |
tol |
the error tolerance |
m |
the maximum number of iterations |
The secant method for root finding extends Newton's method to
estimate the derivative. It will return when the interval between
them is less than tol, the error tolerance. However, this
implementation also stop if after m iterations.
