Help with secant problem

  1. May 5, 2008 #1
    1. The problem statement, all variables and given/known data
    Reduce to a single term:
    I really have been spending a wretched time to solve that
    tan (x/2)*(1+sec x)(1+sec 2x)(1+sec 4x)...................................(1+sec (2^n)x)

    2. Relevant equations

    tan (x/2)=2 tan (x/4) / 1- tan^2 (x/4)

    can this ever help 1+tan^2=sec^2

    3. The attempt at a solution

    Please help!!!!!!!!!! me to get started
