Challenging Math question

  1. Jan 19, 2005 #1
    How does this question work? It's multiple choice so its one of the following answers.

    logx=2cosx, 0<x<2pi

    A. 0.17, 0.71
    B. 1.38
    C. 1.48, 5.07
    D. 1.57, 5.11

    Graphical Solution

    There is an x (in your domain) where these two functions intersect. Graph them and see. (This is a trancendental equation, by the way.)

    If it's multiple choice, why don't you plug in the values in your calc?

    If you want a method, I don't think this can be solved analytically. Do you know any numerical methods?

    That's what I was hoping to find out.
