Complex numbers question

  1. May 30, 2012 #1
    Hello all!
    I'm new in the forum, and in complex numbers so I sorry for my mistakes. I have some questions about complex numbers.

    So can I store two values in complex number for e.g. a particle position and velocity, like [itex]xe^{i\dot{x}}[/itex]? And if this works, after I get the complex number how can I get back the information of I stored in it? In the e.g. I want back the position of the particle?

    Thanks for the answers.

    Welcome to PF, Horv! :)

    You can store 2 real numbers x and y in a complex number by setting z=x+iy.
    Or in your example ##z=x+i\dot x##.

    The exponential form won't work for you, since the imaginary part of the exponent only has the range [0,2pi).

    Position and velocity are usually vectors however.
    And that won't fit in a complex number.
    Then you would need an quaternion number.
