- Bisection method
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.

- Derivative calculator

- 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.

- Fixed-point iteration method
This online calculator computes fixed points of iterated functions using fixed-point iteration method (method of successive approximations)

- Function approximation with regression analysis
This online calculator uses several simple regression models for approximation of unknown function given by set of data points.

- One-variable function graph
This online calculator plots one-variable function graph given function formula and range of variable

- 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.

- Second, third and other derivatives
Evaluates first, second third and other derivatives of a single argument function

- The limit of the function at the given point
This calculator calculates the limit of the function at a given point numerically. It calculates the limit of the function well as x approaches to the specified value. It's not suitable for calculating the limits when x goes to infinity.

- Values of one-variable function
This online calculator calculates values of one-variable function given function formula and set of variable values
