ABSTRACT In this study, a new thirty nine points second order rotatable design in three dimensions is constructed using trigonometric functions and a practical hypothetical example is given by converting coded levels to natural levels. This design permits a response surface to be fitted easily and provides spherical information contours besides the economic use of scarce resources in relevant production processes.

Key words: response surface, rotatable designs, trigonometric functions.
