Trygonometryczne wzory redukcyjne to wzory pozwalające sprowadzić obliczanie wartości konkretnych funkcji trygonometrycznych dowolnego kąta skierowanego do obliczenia wartości funkcji dla kąta ostrego, a następnie dla kąta o mierze z zakresu od 0° do 45°. Brzmi skomplikowanie, prawda? ;) Nie ma się co jednak stresować. Wzory redukcyjne mają ułatwiać życie wszystkim, którzy biorą się za trygonometrię. Dzięki Karolinie poznasz wzory obowiązujące na poziomie liceum i nauczysz się ich wykorzystywania w zadaniach. Wzorom poświęcamy dwa
