Documentation
Arguments
| :: Double | \(h\) to calculate the derivative, as in \(\frac{f(x+h)-f(x)}h\) |
| -> (Double -> Double) | \( f(t_n) \) |
| -> Double | \( t_n \) |
| -> Double | \( t_{n+1} \) |
Single step for Newton’s method for root finding.

\[ t_{n+1} = t_n - \frac{f(t_n)}{f'(t_n)} \]
Useful as a parameter to recurseUntilPrecision.
