Problem with conditional statement in Mathematica

  1. Feb 24, 2010 #1
    I am trying to iterate a solution to a non-linear differential equation - but I am unable to evaluate a statement within a Do loop


    Do[q = Cos[Evaluate[x'/.up]]; If[ q <= 1, Print[q], Print, Print[i^2]], {i, 0.1, 1, .1}]

    x' is a solution to NDSolve

    The output is i^2, which is absurd as q is necessarily <= 1.

    In other words, it's not properly evaluating the conditional statement. I am lost as what to do with this, any help is greatly appreciated.

    edit: I'm using Mathematica 5.0
