How does mathematics describe processes that repeat themselves regularly again and again – the change between day and night, the oscillation of a spring, the height of a gondola on a Ferris wheel? This teaching series for upper secondary level leads from the foundations on the unit circle to the independent modelling of such periodic processes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGuiding question:\u003c\/strong\u003e How do sine and cosine describe periodic processes – from the unit circle to modelling?\u003c\/p\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5 differentiated worksheets with required and optional tasks\u003c\/li\u003e\n\u003cli\u003eFull answer keys with expected solutions\u003c\/li\u003e\n\u003cli\u003eA 7-slide colour presentation\u003c\/li\u003e\n\u003cli\u003eA detailed, step-by-step lesson plan\u003c\/li\u003e\n\u003cli\u003ePrint \u0026amp; digital — editable and ready to use, no prep required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eLearning objectives\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInterpret sine and cosine on the unit circle as the coordinates of a point and give angles in radian measure\u003c\/li\u003e\n\u003cli\u003eDraw the graphs of sin(x) and cos(x) and describe their period, amplitude, zeros and symmetries\u003c\/li\u003e\n\u003cli\u003eInterpret the parameters a, b, c and d in f(x)=a·sin(b·(x−c))+d geometrically and determine their effect on the graph\u003c\/li\u003e\n\u003cli\u003eRead a suitable function term from given graphs of periodic functions and justify it\u003c\/li\u003e\n\u003cli\u003eModel real periodic processes such as daylight length or oscillations with sine or cosine functions and interpret them\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTopics covered (5 worksheets)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSine and cosine on the unit circle and radian measure\u003c\/li\u003e\n\u003cli\u003eDrawing and reading the graphs of sin(x) and cos(x)\u003c\/li\u003e\n\u003cli\u003eApplying the parameters a, b, c and d\u003c\/li\u003e\n\u003cli\u003eAnalysing function terms from graphs\u003c\/li\u003e\n\u003cli\u003eModelling periodic real-world contexts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to use it\u003c\/h3\u003e\u003cp\u003eTeach the full series in sequence or pull single worksheets as stand-alone lessons.
