- Derivative calculator
Online calculator which determines first derivative of a function

- 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.

- Gamma function
Calculation of the Gamma function using Lanczos approximation

- Math equation simplification
Simplifies math equation with single variable (x). In eqation you may also use integer and fractional numerical constants arithmetic operations, trigonometric and hyperbolic functions.

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.

- Mathematical calculator
Mathematical calculator is used for evaluation math expressions with arithmetic operations (+-/*^) and functions: sqrt - square root, exp - exponential function, lb - binary logarithm, lg - decimal logarithm, ln - natural logarithm, sin - sine, cos - cosine, tan - tangent, cot - cotangent, sec - secant, csc - cosecant, arcsin - arcsine, arccos - arccosine, arctan - arctangent, arccot - arccotangent, arcsec - arcsecant, arccosec - arccosecant and others

- 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

- Solving limit problems using L'Hospital's Rule
Solving 0/0 and ∞/∞ limit problems using L'Hospital's Rule.

- 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
