Differntial Mode Equation

  1. Apr 15, 2004 #1
    Hi, I was wondering how you would re-arrange the differntial mode equation :
    Vo=(V2-V1)*(Rf/R1)
    to have V1 as the subject of the formula - its been annoying me for ages.

    thanks

    Well...first of all, divide by Rf/R1
    [tex]\frac{Vo}{Rf/R1}=V2-V1[/tex] THen we just subtract V2 and multiply by -1:
    [tex]\frac{Vo}{Rf/R1}-V2=-V1[/tex]
    [tex]V1=\frac{-Vo}{Rf/R1}+V2[/tex]
