Transformation of a region

  1. May 19, 2008 #1
    Hello. I am trying to work out what the region

    [tex]\{0\leq\tau\leq t,0\leq t<\infty\}[/tex] Is under the transformation:


    I know its just
    [tex]\{0\leq u<\infty,0\leq v<\infty\}[/tex]
    But i am having difficulty showing this.

    [tex]0 \leq v \leq u+v < \infty[/tex] after substituting u, v for tau and t and combining the inequalities.

    Subtracting v from from the above inequalities give: [tex]0 \leq u < \infty[/tex]
    From the first inequality you should be able to see that [tex]0\leq v<\infty[/tex] holds.
