Razones Trigonométricas en el Triángulo Rectángulo

¿Sabías que con solo conocer un ángulo y un lado de un triángulo rectángulo puedes encontrar todos los demás? Eso es exactamente lo que hacen las razones trigonométricas.

En cualquier triángulo rectángulo tenés tres elementos clave: la hipotenusa (el lado más largo), el cateto adyacente (el lado que está junto al ángulo que analizás) y el cateto opuesto (el lado que está frente al ángulo).

Las seis razones trigonométricas principales son:

  • Seno = cateto opuesto / hipotenusa
  • Coseno = cateto adyacente / hipotenusa
  • Tangente = cateto opuesto / cateto adyacente
  • Cosecante = hipotenusa / cateto opuesto
  • Secante = hipotenusa / cateto adyacente
  • Cotangente = cateto adyacente / cateto opuesto

Tip clave: Las tres últimas (cosecante, secante, cotangente) son simplemente las inversas de las tres primeras. Si dominás seno, coseno y tangente, ya tenés la mitad del camino recorrido.

El ejemplo muestra un triángulo con lados 3, 4 y 5. Para el ángulo α, el seno sería 3/5, el coseno 4/5 y la tangente 3/4. ¡Así de simple!

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.

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.
