## Secant Method in R

Intro The main disadvantage of Newton-Raphson Algorithm is that it require the derivative of original function $f'$ . That create a little mess within R implementation . Scant Method excels in that it only requirement of the function is being continuous . Secant Method Essentially , Secant is much alike to Newton-Raphson Algorithm, difference is that will replace the derivative $f'$ with a analogous expression below: $\frac{f(x_{n}) - f(x_{n-1})}{x_{n} - x_{n-1} }$ First Step, we Read more [...]
