Hight Function!

  1. Aug 11, 2005 #1
    Hi guys.

    I was doing a SAC and there were two questions

    one was [tex]y=\frac {1}{X^2}-1[/tex] and the other was [tex]y=\frac {-1}{X^2}+4[/tex]

    I got the hight function to be [tex]h=e^\frac{V}{\pi}-1[/tex] where V is the volume and max hight is 3 for the first function [tex]y=\frac {1}{X^2}-1[/tex]

    Can someone help me to find the hight function of the other function plz.

    The Volume of both graphs are same.

    Thanx in advance.

    is this the hight function of second function??? [tex]h=e^\frac{-V}{\pi}-4[/tex]

    would you mind defining a 'hight' function. I can find no references for it (other than misspelling it as height when it is defined for abelian groups according to planet math)

    [tex]y= \frac{1}{X^2}-1[/tex] is not a question- it is a function or equation. What was the question??

    I didn't know a graph had a volume! I assume "hight" was a misprint for "height" but I'm still not sure what you mean by the "height" of a function.

    Sorry about my BAD english but all I intended to say is how can I find the rate of change of height with respect to change in volume from the second equation.

    Hope that makes it abit more clear.
