cosβ=x/x
tgβ=y/x
ctgα=x/y
c)
sinγ=|BC|/|AC|
cosγ=|AB|/|AC|
tgγ=|BC|/|AB|
ctgγ=|AB|/|BC|
d) h-WYSOKOŚĆ CAŁEGO Δ
sinδ=h/a
cosδ=c/a
tgδ=h/c
ctgδ=c/h
zadanie 2
a)
sinα=2/√13=2√13/13
cosβ=3/√13=3√13/13
tgβ=3/2=1 1/2
ctgα=3/2=1 1/2
ctgβ=2√6 / 2√2=√6/√2=√12/2
cosα=2√2/6=√2/3
sinβ=2√2/6=√2/3
tgα=2√6 / 2√2=√6/√2=√12/2
