Homework Help: More on Numerical Methods

  1. Sep 26, 2005 #1
    Find the intervals containing solutions to the following equation

    [tex] 4x^2 - e^x = 0 [/tex]
    I haven o clue on where to start really?
    WOuldi expand e^x using taylor series? i mean one could do this
    [tex] x - 2ln x = ln 4 [/tex]
    so then would i do log expansion by taylor series? Or would i use bisection method? But how owuld i pick the two points for bisection method? Please assist!

    And as always, your help is greatly appreciated!

    Why not just plot:

    [tex]y1(x)=4x^2[/tex]

    and

    [tex]y2(x)=e^x[/tex]

    interesections, bingo-bango.
