    Functions in Excel

    I'm not really very familiar with excel, so I need a lil bit of help.

    I'm trying to make a graph of the function:

    y=1-[ (1-x)^10 + 10x(1-x)^9 + 45x^2(1-x)^8 ]

    and I want to vary x from 0 to 1,aka 0<x<1.

    If someone could give me some basic instructions, your help would be much appreciated.

    take 2 columns and say 100 rows

    in the first column and first row, A1 type 0. Go down one row to A2 and type =(A1+.01) and hit enter. .01 shoudl show up. Then click on the corner of A2 and drag the box down to A100. you should then have 0-1 in incriments of .01.

    Goto B1 and type in your equation as =(your equation here) only substitute A1 for X

    Again drag the corner of B1 down to B100...no you should have all your Y values

    Now highlight A1,B1 - A100, B100 and hit the graph button, select the graph you want.


    geez..im gonna go do it now lol



    btw, there is probally a function button do jsut do it simply..this is jsut one way to do it.

    Thanks Billy, got them perfect and everything checks out with the manual calculations too. I wish I knew more excel because I know it is very helpful for a wide range of things but I don't know of any ways to really get more familiar with it and its hard to figure some of these things out on your own.

    Anyways, thanks again.
