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.
Linear approximation
This online calculator derives the formula for the linear approximation of a function near the given point, calculates approximated value and plots both the function and its approximation on the graph
Number approximation as a sum of unit fractions
The calculator approximates a fractional number with a sum of unit fractions (a unit fraction numerator is one). The unit fraction denominator is a number which is less than the base times the base in integer non negative power.
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.
