sin(α + β) = sinα cosβ + cosα sinβ

cos(α + β) = cosα cosβ – sinα sinβ

tg(α + β) = (tgα + tgβ)/(1 – tgα tgβ)

ctg(α + β) = (ctgα ctgβ – 1)/(ctgβ + ctgα)

sin(α – β) = sinα cosβ – cosα sinβ

cos(α – β) = cosα cosβ + sinα sinβ

tg(α – β) = (tgα – tgβ)/(1 + tgα tgβ)

ctg(α – β) = (ctgα ctgβ + 1)/(ctgβ – ctgα)
