National 5 Working with the graphs of trigonometric functions Phase angle Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

National 5 Working with the graphs of trigonometric functions Translation (sliding a curve along an axis) Trigonometric graphs can be sketched when you know the amplitude, period, phase and ...

In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. The author ...
