- False position method
False position method - is a root-finding algorithm that uses a succession of roots of secant lines combined with bisection method to approximate a root of a function f.

The bisection method in mathematics is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing. The method is also called the interval halving method.

- Root and power
This calculator outputs desired root and power of entered number

- Secant method
The secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.
