  -> tuple[float, float]

Root finder \(f(x) = 0\).

Parameters:

methodstr

Root finding method (dichtomy or bisection).

f(float) -> float

\(f(x) : \mathbb{R} \to \mathbb{R}\).

x_initfloat

Initial value for \(x\).

y_valuefloat

Target value for \(y\).

precisionfloat

Precision for algorithm.

delta_xfloat

Increment of \(x\).

max_loopsint

Max number of iterations.

x_namestr

Name of \(x\) variable.

y_namestr

Name of \(y = f(x)\) variable.

verbositybool

Turn on/off logging.

Returns:

tuple[float, float]

\(x, f(x)\) where \(f(x) = y\).
