Diagram that illustrates the formula for sine and cosine of sum of angles
Summary[edit]
| Description |
Polski: Przyjmij, że zaznaczony (pogrubiony) odcinek ma długość 1. Wyraź długości pozostałych boków trójkąta, do którego ten odcinek należy, jako funkcje kąta ostrego. Opierając się na już obliczonych długościach boków wyznacz długości pozostałych odcinków na diagramie. Na końcu zbadaj trójkąt, którego kąt ostry to α + β. Zobacz, jak można obliczyć jego sinus i cosinus.
English: Assume that the length of the bold-marked segment is equal to 1. Express the length of the other side of the triangle to which this unitary segment belongs as functions of the acute angle. Basing on already computed lengths, find lengths of the other segments in the diagram. Finally check the triangle whose acute angle is α + β. See how to compute its sine and cosine. |
