The replacement of a Transcendent Function in a given interval by a polynomial function using Newton's Polynomial Interpolator

The work deals with the substitution of a transcendental function by polynomial one, determined through Newton's Interpolator polynomial, in certain interval, so that characteristics space have performance similar to original function. Research enables numerous applications scientific field, as functions allow better predictability display their graphics well entry analytical points and results are easy manipulate display. Some examples application calculation integrals were presented, presenting calculations obtaining interpolating A comparative table was displayed four functions, equally acceptable results. these integral allows errors possibly margin pre-established intervals.
