Abstract

This thesis is designed to study on teaching method of trigonometric fuction by using circles (especially unit circle). For Problems using trigonometric functions in high school courses - especially problems regarding trigonometric equation and trigonometric inequality - graphs are generally used as problem solving tasks. However, these problem solving tasks can be replaced by solutions using circles. By using circles, students can understand trigonometric function more intuitively and fundamentally. In chapter Ⅲ, teaching methods in trigonometric function units in 2007 Revised Curriculum『Math』and『MathⅡ』 have been analyzed. In chapter Ⅳ, new problem solving tasks using circles have been studied and suggested for problems usually solved by using graphs and algebraic methods in those units in texts『Math』and『MathⅡ』.
