Answers to Questions (FAQ)
How to observe the equation of a bend?
To find the equation from a graph:
Method 1 (plumbing equipment): analyze the bend (by looking at it) in guild to make up one's mind what type of function it is (rather linear, exponential, logarithmic, periodic etc.) and point some values in the table and dCode volition find the function which comes closest to these points.
Method ii (interpolation): from a finite number of points, in that location are formulas allowing to create a polynomial which passes exactly through these points (see Lagrange interpolation), point the values of sure points and dCode will calculate the passing polynomial by these points.
How to find an equation from a fix of points?
To derive the equation of a function from a table of values (or a bend), there are several mathematical methods.
Method 1: detect remarkable solutions, like remarkable identities, it is sometimes piece of cake to observe the equation by analyzing the values (past comparison 2 successive values or past identifying certain precise values).
Example: a function has for points (couples $ (x,y) $) the coordinates: $ (one,ii) (two,4), (3,6), (iv,8) $, the ordinates increase by 2 while the abscissas increment past 1, the solution is piddling: $ f (10) = 2x $
Method 2: use a interpolation function, more complicated, this method requires the use of mathematical algorithms that can find polynomials passing through any points. The most well known interpolations are Lagrangian interpolation, Newtonian interpolation and Neville interpolation.
NB: for a given set of points there is an infinity of solutions because at that place are infinite functions passing through certain points. dCode tries to propose the about simplified solutions possible, based on affine office or polynomial of depression degree (caste 2 or 3).
