Solving for x

  1. Oct 24, 2007 #1
    1. The problem statement, all variables and given/known data
    1 = absolute value( (sin(x)-x)/(sin(x))) * 100

    2. Relevant equations
    Don't think there are any.

    3. The attempt at a solution
    I decided to do it graphically, so i graphed y=.01 and y= absolute value(1-(x/sin(x))
    I got x = .244 radians for the intersection and I am just not sure if it is correct because i can manipulate the equation so that they never intersect or I can manipulate it so the point changes.

    Be more specific. How did you manipulate the equation?

    In order to see the problem better..

    [tex] 1= |(\frac{\sin(x)-x}{\sin(x)})(100)| [/tex]

    ya thats it I don't know how to do that fancy typing stuff

    when i put it in mathematica
    "FindRoot[1 == Abs[((Sin[x] - x)/Sin[x])]*100, {x, 0.1}]"
    i get
    {x -> 0.244097}
    which makes sense
