Abstract: In this paper, specific Value (ζ -a/b-a) of ζ in Lagrange's mean Value therocm, Cauchy's .b-a mean value therocm and exlend form of first mean value theorem of integotion converge to rate of 1/2 have been obtained (when end point of intcrval b➢a).
Key Words: Lagrange's mean value therocm; Cauchy's mean value therocm, first mean vailue theorcm of integotion; Taylor's formula; function of primary.
