三角函数在图案元素设计上的应用

从计算机编程的角度，举例说明常见的三角函数在图案设计应用中的重要性，并提出3种基本方法来实现，分别为描点法、直线法和色彩法，最后给出了一个具体应用，即企业商标的设计．

Application of Trigonometric Function on Pattern Elements Design

From the computer programming's angle,the paper attempts to illustrat e the importance of the common trigonometric function to the design(pattern)with examples,and proposes some basical methods in the design.They are painting poin t and drawing the straight line.At last,the paper give out a concrete applicatio n,that is to say,the design of the trade mark of the enterprise.
