Homework Help: Rearranging equation to find back gate bias

  1. Apr 6, 2012 #1

    I am having a bit of an issues rearranging an equation for my solid state electronics class. I seem to have a mental block with this sort of stuff, so I am hoping someone can help.

    The equation is

    0.34 = 1.05((0.64 + |VBS|)1/2 - (0.64)1/2)

    I know the usual stuff, like + to a - when moving across the equals sign, so it is more the power and what have you.

    Thanks in advance.

    Divide both sides by 1.05.
    Simplify √0.64, and then add that amount to both sides.
    Continue from there.

    That did it ...for some reason, I was multiplying 1.05 by the bracket, and going from there ...which was just making things complicated.

    Again, thanks!!
