Trigonometri Temel Bağıntıları

Trigonometri, dik üçgenlerdeki açı ve kenarlar arasındaki ilişkiyi anlamamızı sağlar. Bir dik üçgende sin, cos, tan ve cot değerleri açının karşısındaki kenar ile hipotenüs arasındaki ilişkilerdir:

  • Sinüs (sin) = Karşı dik kenar / Hipotenüs
  • Kosinüs (cos) = Komşu dik kenar / Hipotenüs
  • Tanjant (tan) = Karşı dik kenar / Komşu dik kenar
  • Kotanjant (cot) = Komşu dik kenar / Karşı dik kenar

Dik üçgenlerde Pisagor Teoremi de unutulmamalıdır: a² = b² + c² hipotenu¨s2=dikkenar12+dikkenar22hipotenüs² = dik kenar1² + dik kenar2². Ayrıca bütünler açılar için x+y=90°x + y = 90°, sin x = cos y ve tan x = cot y özel ilişkileri geçerlidir.

İpucu: Trigonometrik değerleri ezberlemek yerine, 30°, 45° ve 60° için özel üçgenleri hatırlayarak hesaplayabilirsin. 45° açılı üçgen 1-1-√2 kenarlarına, 30°-60° üçgeni ise 1-√3-2 kenarlarına sahiptir.

45° için değerler:

  • sin 45° = cos 45° = √2/2
  • tan 45° = cot 45° = 1

30° ve 60° için değerler:

  • sin 30° = 1/2, cos 30° = √3/2, tan 30° = √3/3, cot 30° = √3
  • sin 60° = √3/2, cos 60° = 1/2, tan 60° = √3, cot 60° = √3/3

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.

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 KlichAndroid 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.
