labview equation box quadratic equation : labview

Hello to all tge members,
 
Currently, i'm on my intership and my intern includes programming using LabView 7.1. So, i just got to know this sofware last week. In order to programme, i need to get used to this software and of course, create some programs. I've done an exemple/exercice and i'm having a single error which bugs me so bad!
Well, it goes something like this:
 
I wanted to visualise a graph of an quadratic equation : y=ax²+bx+c
the a,b,c,and x are all variable. when i used the equation box, i entered this equation (y=a*x^2+b*x+c) with 4 inputs(a,b,c,x) and an output(y). I linked this box to the icon graph and lastly, i tried to execute it. Unfortunely, it appeared this error " y=a*x^2+b*x+c;#"  and it said, whole type necessary(it's a direct translation from french) something like that.
 
So please do help me please. Thank you in advanced!

Hi Dhirah,you should try "x**2" (standard C syntax!) instead of "x^2":smileywink: You can also transform your formula into y=((a*x)+b)*x+c avoiding power functions.And maybe try to use basic LabView functions instead of formula node right from the beginning, may make things easier later on...Message Edited by GerdW on 04-01-2008 11:01 AM

Hi Dhirah,
do you use the formula node? If yes x^2 is not possible, use pow(x, 2) instead of it.
