This paper analyses several characters of derivativefunction, presents effective methods to discuss existential conditions of primitive function and gives number of facilitated conclusions.
By using the statistic properties of the correlation coefficient, a curve correlation coefficient is calculated, and then the matching point is obtained through evaluating it's derivativefunction.
