Rate of Convergence of the Sine Imprecise Functions

We convert polynomial function of degree n th into imprecise form to obtain an important point called conversion point. For some particu lar reg ion, we co llect the finite number of data points to obtain the most economical function called imprecise function. Conversion point of the functions is shown with the help of MUPAD graph. Further we study the area of the imprecise function occurred by the multip licat ion of sine function to know how much variation o f the imprecise functions are obtained for the respective intervals. For different imprec ise polynomial we study level of the rate of convergence.
