Deduction of Equations

  1. Nov 29, 2004 #1
    Hello everybody...

    First of all I would like to know if anyone is spanish-speaking or lives in Mexico.

    Second of all, I wanted to know if anyone knows about deducing equations I really need them, for my university.

    Any page or book would be greatly appreciated.

    On-line teaching or self-learning could be good too.

    Soy de nueva york, pero hablo español. No sé lo que estás preguntando...cuál ecuaciones quieres deducir? La cuestión no me es claro..

    ...deducción...

    Hola, que bueno que contestaste !!!

    El problema está que recientemente entré a un curso de matemáticas, pero el profesor, avanza demasiado rápido y cualquier ecuación que vemos, ( sea la ley de snell, n1sen#1 = n2 sen#2 ) el profesor la empieza a deducir, y empieza a escribir otras ecuaciones, que junto con otras ecuaciones se cancelan y poco a poco va demostrando que solo quedan las n´s y los senos, y ya se forma la ley de snell !!!

    Espero que entiendas !!!

    Eso es mas o menos lo que necesito aprender, a deducir, saber de donde vienen, etc...

    Entiendo lo que me dijiste...pero no puedo ayudarte. Sólo estoy en secundario así que no sé bastante sobre la tema que estás estudiando. Estoy estudiando Calculus I. Recomiendo que preguntes a tu profesor cómo la dedujo. Eso es todo que puedo decir, lo siento.

    either that, or ask us in english. let me make one point clear: if you want to do mathematics in todays world, you must read write and speak and understand english. it is the universal language of science.

    probably anyone here but me can explain snells law.

    Here is a translation for everyone:

    The problem is that recently I entered a course of mathematics, but the profesor advances too quickly and any equation that we see (it is the law of snell n1sin1=n2sin2) the profesor begins to deduce it, and begins to write other equations, that together with other equations cancel each other and little by little he is demonstrating that only the n's and sines remain, and now the law of snell is formed.

    That is more of less what I need to learn, to deduce, to know where they came from, etc...

    If someone could help him with the math I can translate anything he doesn't understand english wise...

    Yo soy de México.

    Hola, yo estudio fisica en la UNAM, entro mas o menos seguido aqui. No soy un genio pero si quieres preguntar algo aqui, yo tratare de ayudarte.
