Based on arc and projection principle,we design a system model of sine and cosine curve drawing. This paper introduces the structure of system model,makes an analysis of main parameters in the system and describes the working principle of the system,in com-bination with the function y=sinx and y=cosx images,and depicts the working process of the model in detail. For early phase,period and amplitude of the function,the use of the model are presented.
