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

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 |

Derivative It finds one variable function derivative. Step by step differentiation solution is also provided. |

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 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. |

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

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

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

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

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. A brief secant method description can be found below the calculator |

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

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. |

Gamma function Calculation of the Gamma function using Lanczos approximation |

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

Function graphs The calculator plots several function graphs on the single coordinate plane. |

Newton's method This online calculator implements Newton's method (also known as the Newton–Raphson method) for finding the roots (or zeroes) of a real-valued function. |

Noisy function generator This online calculator takes function, calculates its values for given range and then adds some random noise to distort original values. |

Curve fitting using unconstrained and constrained linear least squares methods This online calculator builds a regression model to fit a curve using the linear least squares method. If additional constraints on the approximating function are entered, the calculator uses Lagrange multipliers to find the solutions. |
