Razones Trigonométricas

Los triángulos rectángulos tienen un ángulo de 90° y la suma de sus tres ángulos siempre es 180°. En estos triángulos identificamos la hipotenusa (el lado más largo, opuesto al ángulo recto) y los catetos (los otros dos lados). Cuando calculamos razones trigonométricas, trabajamos con los ángulos agudos, nunca con el ángulo recto.

Las tres razones trigonométricas principales son seno, coseno y tangente. El seno (sen) de un ángulo es igual al cateto opuesto dividido entre la hipotenusa: Sen α = co/h. El coseno (cos) es el cateto adyacente dividido entre la hipotenusa: Cos α = ca/h. La tangente (tan) se calcula como el cateto opuesto dividido entre el cateto adyacente: Tan α = co/ca.

💡 Un truco para recordar estas razones: "SOH-CAH-TOA". Seno = Opuesto/Hipotenusa, Coseno = Adyacente/Hipotenusa, Tangente = Opuesto/Adyacente.

Algunos valores importantes para memorizar son: Para 30°, el sen = 1/2, cos = √3/2, tan = √3/3. Para 45°, sen = cos = √2/2, tan = 1. Para 60°, sen = √3/2, cos = 1/2, tan = √3. Estos valores te ayudarán a resolver problemas sin necesidad de calculadora.

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.
