Oblicz wartości funkjcji trygonometrycznych kąta α w trójkącie prostokątnym na rysunku poniżej:
a=12
b=5
ax^{2}+bx^{2}=cx^{2}
12x^{2}+5x^{2}=cx^{2}
144+25=cx^{2}
169=cx^{2}
c=13
sin\alpha=a/c
sin\alpha=12/13
cos\alpha=b/c
cos\alpha=5/13
tg\alpha=a/b
tg\alpha=12/5
tg\alpha=2 2/5
ctg\alpha=b/a
ctg=5/12
