### Goniometrické funkce

y = cosα

Df < 0⁰ ; 360⁰ >

Hf <-1 ; 1>

- grafem je cosinusoida

= x- ová souřadnice průsečíku ramene úhlu s jednotkovou

kružnicí

α = 45⁰ 20ʹ

β = 14⁰ 30ʹ

γ = 85⁰ 10ʹ

δ = 50⁰ 40ʹ

α = 4⁰ 10ʹ

β = 90⁰

γ = 66⁰ 10ʹ

δ = 10⁰ 50ʹ

α = 39⁰ 20ʹ

β = 18⁰ 30ʹ

γ = 8⁰ 40ʹ

δ = 55⁰ 10ʹ

cos⁡α = 0,5

cos⁡α = 0,2079

cos⁡α = 0,9696

cos⁡α = 0,6088

cos⁡α = 0,9205

cos⁡α = 0,5025

cos⁡α = 1

cos⁡α = 0,2051

cos⁡α = 0,8936

cos⁡α = 0,5544

cos⁡α = 0,4752

cos⁡α = 0,5831

( α – po 10⁰ ).
