版社 2006年出版some ways to caculating the maximun and minimum in trigonometric functionYang Lixian, Instructor: Xie Shaolong(Department of Mathematics, YuXi Normal University, Grade 2004,Class 1, No. 2004021107) [Abstract]: The trigonometric function is an important function concept in mathematics. The mastery of the trigonometric function plays an impotant role in learning mathematics well. The trigonometric function is closely related to other mathematical knowledge and widely used in learning and studying other mathematical knowledge. In the trigonometric function studying, the ways to caculating the maximun and minimum in trigonometric function are very important. It is significant to discuss and sumarize the ways to caculating the maximun and minimum in trigonometric function in learning trigonometric function.[Key words]: trigonometric function ,maximun and minimum, ways of caculating10
