Trigonometri Formülleri

Trigonometride en önemli formüller toplam ve fark formülleridir. Bunlar sayesinde karmaşık açıları daha basit parçalara ayırabilirsiniz:

  • sinA+BA+B = sin A cos B + cos A sin B
  • cosA+BA+B = cos A cos B - sin A sin B
  • tanA+BA+B = tanA+tanBtan A + tan B/1tanAtanB1 - tan A tan B

İki kat açı formülleri ise bir açının iki katının trigonometrik değerlerini bulmanıza yardımcı olur. Örneğin:

  • sin 2x = 2 sin x cos x
  • cos 2x = cos²x - sin²x = 2cos²x - 1
  • tan 2x = 2tan x/1tan2x1 - tan²x

💡 İpucu: Trigonometrik fonksiyonların teklik-çiftlik özelliklerini hatırlayın: sin, tan ve cot tek fonksiyonlardır F(x)=F(x)F(-x) = -F(x), cos ve sec çift fonksiyonlardır F(x)=F(x)F(-x) = F(x).

Denklem çözümlerinde genel çözüm formülleri hayat kurtarır. Örneğin:

  • sin x = 0 ise x = nπ
  • cos x = 0 ise x = 2n+12n+1π/2
  • sin x = sin y ise x = nπ + (-1)ⁿy

Ayrıca a sin x + b cos x gibi bir ifadenin maksimum değeri +√a2+b2a²+b², minimum değeri ise -√a2+b2a²+b² olduğunu unutmayın. Bu tür ifadeler sınavlarda sıkça karşınıza çıkacaktır.

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.
