# Goniometrické funkcie

1. Prehľad a úvod

Goniometrické funkcie sú super dôležitá časť matematiky, ktorá sa zaoberá
vzťahmi medzi uhlami a

Základné definície a jednotková kružnica

Predstav si jednotkovú kružnicu - to je kružnica so stredom v bode [0,0] a polomerom r = 1. Je to tvoj hlavný nástroj na pochopenie goniometrie!

Keď máš bod P(x,y) na tejto kružnici, tak sínus uhla α je jednoducho y-ová súradnica tohto bodu a kosínus je x-ová súradnica. Takže sin α = y a cos α = x.

Tangens a kotangens sú trochu zložitejšie. Tangens je pomer tg α = sin α/cos α, zatiaľ čo kotangens je cotg α = cos α/sin α. Dávaj pozor - tangens nie je definovaný tam, kde cos α = 0!

Tip: Zapamätaj si prevod uhlov: 180° = π radiánov. Na prevod zo stupňov na radiány vynásob číslom π/180.

Pytagorova veta a základné vzťahy

Z jednotkovej kružnice vyplýva najdôležitejší vzťah v goniometrii: sin²α + cos²α = 1. Toto je Pytagorova goniometrická veta a bez nej sa nezaobídeš!

Ďalšie užitočné vzťahy, ktoré si treba zapamätať: tg α · cotg α = 1 (keď sú obe definované) a sin(π/2 - α) = cos α. Tiež si všimni, že cos(-α) = cos α (kosínus je párna funkcia) a sin(-α) = -sin α (sínus je nepárna funkcia).

Pre rýchle riešenie úloh si zapamätaj hodnoty pre dôležité uhly: sin 30° = 1/2, cos 30° = √3/2, sin 45° = cos 45° = √2/2, sin 60° = √3/2, cos 60° = 1/2.

Vlastnosti funkcií sínus a kosínus

Funkcia sínus má obor hodnôt <-1, 1> a periódu 2π. Jej graf vyzerá ako vlnka, ktorá začína v nule a stúpa. Je to nepárna funkcia, takže sinx-x = -sin(x).

Funkcia kosínus má rovnaké vlastnosti, len je posunutá - začína v hodnote 1. Je to párna funkcia, takže cosx-x = cos(x). Vlastne platí, že cos x = sinx+π/2x + π/2.

Obe funkcie majú nulové body - sínus v bodoch x = kπ a kosínus v bodoch x = π/2 + kπ, kde k je celé číslo. Tieto body sú super dôležité pri riešení rovníc!

Poznámka: Graf kosínusu je vlastne graf sínusu posunutý doľava o π/2.

Funkcie tangens a kotangens

Tangens je už trochu iný - má obor hodnôt celé reálne čísla R, ale nie je definovaný v bodoch x = π/2 + kπ. Tam má zvislé asymptoty a jeho perióda je len π.

Kotangens je podobný, len nie je definovaný v bodoch x = kπ. Obe funkcie sú nepárne, takže tgx-x = -tg(x) a cotgx-x = -cotg(x).

Na grafoch uvidíš, že tangens rastie od -∞ do +∞ v každom intervale dĺžky π, zatiaľ čo kotangens klesá. Nulové body tangensa jsou v bodoch x = kπ a kotangensa v bodoch x = π/2 + kπ.

Goniometrické funkcie sú super dôležitá časť matematiky, ktorá sa zaoberá
vzťahmi medzi uhlami a

Znamienka v kvadrantoch a praktické riešenie

V I. kvadrante 0azˇπ/20 až π/2 sú všetky funkcie kladné. V II. kvadrante π/2azˇππ/2 až π je kladný len sínus. V III. kvadrante πazˇ3π/2π až 3π/2 sú kladné tangens a kotangens. V IV. kvadrante 3π/2azˇ2π3π/2 až 2π je kladný len kosínus.

Pri riešení úloh s uhlami nad 90° používaj referenčný uhol - to je uhol medzi daným lúčom a osou x. Potom len priraď správne znamienko podľa kvadrantu.

Napríklad pre 150°: referenčný uhol je 30°, si v II. kvadrante, takže sin 150° = +sin 30° = 1/2, ale cos 150° = -cos 30° = -√3/2.

Trik: Zapamätaj si "CAST" - v kvadrantoch I, II, III, IV sú postupne kladné: Cosinus, All (všetky), Sinus, Tangens.

Riešené príklady a aplikácie

Pri zjednodušovaní výrazov často používaj Pytagorovu vetu sin²x + cos²x = 1. Napríklad 1cos2x1 - cos²x/1cosx1 - cos x = sin²x/1cosx1 - cos x = 1cosx1 - cos x1+cosx1 + cos x/1cosx1 - cos x = 1 + cos x.

Na určenie oboru hodnôt si pamätaj základné rozsahy: keď máš f(x) = 3sin x - 2, tak z -1 ≤ sin x ≤ 1 dostaneš -3 ≤ 3sin x ≤ 3, a po odčítaní 2 máš -5 ≤ f(x) ≤ 1.

Jednotková kružnica je tvoj najlepší kamarát - ak ju dobre pochopíš, nemusíš si pamätať všetky vzorce. Stačí si predstaviť bod na kružnici a jeho súradnice ti dajú sin a cos daného uhla.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Stefan S

iOS user

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

iOS user

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

Android user

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
