Homework Help: How to rearrange this equation for o

  1. Jun 7, 2008 #1
    o = theta

    how the hell do you rearrange for o?

    (1/6)tan^2(o/2) + (1/2)tan^2(o/2) = t

    Are both functions tan^2(o/2)?

    If so, what is the associative rule when functions are the same, i.e. a f(x) + b f(x) ?

    Sorry i made a mistake, it' really:

    (1/6)tan^2(o/2) + (1/2)tan(o/2) = t

    If you let x= tan(o/2) then the equation is (1/6)x2+ (1/2)x= t or, equivalently,
    x2+ 3x- 6t= 0. Can you solve that for x (in terms of t)?
