Szczegółowe wyjaśnienie:
1.
a)
sin α = 6/10 = 3/5, cos α = 8/10 = 4/5, tg α = 6/8 = 3/4, ctg α = 4/3
b)
sin α = 7/25, cos α = 24/25, tg α = 7/24, ctg α = 24/7
c)
sin α = 1/√17 cos α = 4/√17 tg α = 1/4 ctg α = 4
d)
sin α = 1/4 cos α = √15/4 tg α = 1/√15 ctg α = √15/1 =√15
e)
sin α = √5/5 cos α = 2√5/5 tg α = 1/2, ctg α = 2
f)
sin α = √2/√6 cos α = 2/√6 tg α = √2/2 ctg α = 2/√2
