Name
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.
