Applied Mathematics and Sciences: An International Journal (MathSJ) ISSN : 2349 - 6223 P.Seshu Babu,A.V.Dattatreya Rao, G.V.S.R. Anjaneyulu and K.Srinivas ABSTRACT Response Surface Methodology (RSM) has applications in Chemical, Physical, Meteorological, Industrial and Biological fields. The estimation of slope response surface occurs frequently in practical situations for the experimenter. The rates of change of the response surface, like rates of change in the yield of crop to various fertilizers, to estimate the rates of change in chemical experiments etc. are of interest. If the fi...
